uTorrent freezes and cannot be killed.

Recommended Posts

I have for a while have had some problems with uTorrent crashing from time to time (maybe about every other day). Also some problems with some torrents halting cause of some error with access to memory (sorry but don't remember exactvly).

But today I can't use uTorrent at all. The program freezes after just a couple of minutes and can't even be killed from task manager or process explorer. Seen that some people have hade the same symptoms with Norman Internet Security, but I don't have that program. Actually I have'nt installed anything new today at all. I have run a AVG Anti-Virus scan but it could'nt find anything...

EDIT: More info

I have now rebooting the computer once more and started uTorrent. It seemed to work for a couple of minutes and seeded at 7MB/s , but after a while all the seeding just dies out. Only one torrent keeps on downloading, at about 30-40kB/s, but all torrents seem to connect to a lot of peers. Also a re-check of a torrent stopped and when I tried to force it doing a re-check uTorrent freezed and cannot be killed again :/

Hi, thanks for the answer.

The settings in uTorrent should be ok as it has been working with my 100MBit connection for a while now (had to make some changes to the settings from the begginining to not get "Disk overload"). When uTorrent works (as it does for the most) I've been able to download and upload simultaneously at 10Mb+/s.

The setttings for net.max_halfopen is 43, cache size is 1500MB (if I have it a couple of hundred MB higher uTorrent crashes when cache fills it up).

I actually have found a strange "reason" for this freezing. It only happens when a re-check on a 30GB+ torrent hits 11.9% ! I stopped the download of that torrent and restarted computer once more and now uTorrent seems to be working. Anyone can explain this ??

As I said in the last post this total freezing and not being able to kill it is a recent problem, but I had sporadical crashing of uTorrent for a while now.

Here is a DLL log of uTorrent from ProcessExplorer:

"cache size is 1500MB (if I have it a couple of hundred MB higher uTorrent crashes when cache fills it up)."

uTorrent, being a 32bit app, cannot handle more than 2 GB of memory space. It will crash trying to exceed that...which may happen before the cache size is greater than 1800 MB. In the past, there were even problems with the cache being larger than ~1000 MB. I am not sure those problems are completely solved. :(

Search indexers can cause problems:

Since upgrading to Vista a couple of months I had a problem whith my internet connection going down and needing being reactivated again. I solved this by upgrading NIC's drivers from Realteks homepage, so I already have the newest (or at least very new) drivers.

As I mentioned, the immediate problem I had today is solved. uTorrent froze on a re-check of a (very large) torrent !? By stopping that torrent uTorrent has been working, and I already uploaded 120GB and downloaded 60GB in the hours since.

But I still would like to know why a re-check of one torrent makes uTorrent freeze and impossible to kill ? Also as I wrote uTorrent hasn't been totally stable for me before either, with crashing approximately every other day and I would like that also getting solved, but I guess I'll probably have to come back with some info next time that happens.

If you try to re-check it again, does it continue to happen?

The problem with computers (and electronics in general), is that something that's 100% perfect might still glitch now or then. If you had a perfect processor (which doesn't exist), and perfect memory (which doesn't exist), and a perfect motherboard (which doesn't exist), and perfect hard drives (which don't exist), given our current way of doing things, sometimes things will still glitch now and then. It relates to the fact that computers work on 1's and 0's and sometimes a 1 just isn't oney enough or a zero isn't zeroey enough, so the computer guesses. If it guesses wrong, things break down. If it's a very critical bit that goes wrong, the application may crash the entire thread, making it impossible to terminate. In that state, it's known as a Zombie Process, because it can't be killed.

Now if a problem is reproducible a large percent of the time, there's obviously an underlying problem that's needs to be addressed. To answer your question as to "why", we need to know if the problem is reproducable. If yes, we can troubleshoot it. If not, then.......the why is whatever you want to call it. Voodoo, magic, the demon in the machine, karma, bad luck, etc. I mean, if glitches would happen using perfect hardware given our current level of technology (which most engineers would agree on), then when you have processors that contain page after page of errata (and page after page of undocumented errata) and are STILL the best produced hardware out there, glitches are definately going to occur from time to time.

Sorry I have been very busy so haven't had time to spare to combat uTorrent.

But yes, the problem happens once in a while, that is:

1. uTorrent freezes and cannot be killed

2. After a restart of computer uTorrent freezes when it reaches a specific percentage in re-check of a file.

But now I have an even more serious problem, it seems that uTorrent cannot read and write from harddisk anymore. I've had some problems with "Disk overloaded", when I check with perfmon and in uTorrent Speed-tab it seems that uTorrent is'nt writing to disc at all !? In that situation i close uTorrent but the process is still running and cannot be killed, so a reboot of computer is needed.

Today though, I cannot make it work even after a reboot. Re-check of torrents is at 0% and not moving, when I download I fastly fill upp the cache (1GB) and after that get of course the famous "Disk overload" and as usually have to reboot computer to be able to kill the uTorrent process. The torrents are not seeding either, so it really seems like that uTorrent cannot access my harddrives.

I really don't know what to do now, I have run chkdsk on my harddrives but that didn't help at all.

Yes I have, and for the most it is working even with a lot of torrents and hundreds of connections in total at over 10MB/s both downloading and uploading. So I really don't think the problem is that.

And the problem right now is NOT that uTorrent is writing/reading the harddrives slowly, it seems that uTorrent cant get any access at all to the drives.

I'm using UDMA-5.

Please trust me, the problem is not harddisk bandwidth.

Actually, after a 100:th restart of uTorrent (and that is a reboot) suddenly uTorrent start reading the files (that is start seeding and re-checking). As I can see in the "Speed"-tab it also seems to be writing out data to disc to.

Just like that... Weird. But I'm sure the problems will come back. All files have'nt rechecked yet, so maybe I'll get a problem of the first kind to (that is uTorrent freezes when recheck reachs a specific percentage on a specific torrent).

EDIT:

Argh. Had to restart the computer (cause of an unrelated madder) and now the problem is back.

uTorrent seems to be unable to neither read or write to discs.

EDIT2: Is there any logs that you can recommend me to check ?

Not that it would be easy to do, I'd try various Sysinternals.com tools (that's where you got Process Explorer from)...

FileMon might spot when uTorrent tries to read or write from disk and fails...and maybe even have an error message for why.

Windows event monitor might also give clues.

Since last night uTorrent has been working for this 24 hours like a charm (uploaded 500gb). But now I was creating a new torrent and suddenly all uploads stopped and the download is slowly filling up the cache without writing it out to disk. Also the creation of a new torrent paused (and cannot be canceled either).

I'm now looking in Process Monitor, and the only strange things I can see is a couple of :

"04:23:31,2978773 uTorrent.exe 4252 WriteFile C:\Users\*****\AppData\Roaming\uTorrent\resume.dat.new FAST IO DISALLOWED Offset: 57, Length: 292 084"

This is recurring, but there are much more WriteFile operations to resume.dat.new that have SUCCESS.

What does FAST IO DISALLOWED mean ?

EDIT:

There doesn't seem to be any kind of attempts to read or write any of the data files (that is files within torrents).

EDIT2:

I rebooted the computer and everything started fine, uploading, downloading and re-checking. I then tried creating a new torrent, and the problem reaccured again. So.. have to reboot again. Totally not cool.

I just tried to run Hijackthis while uTorrent was in this strange mode, but first i got an error halfways (which I took a screenshot of, but onfortunatly forgot to save to a file :/ ). I then tried a couple of more times and didn't got the error, but Hijackthis just froze at this point :

O4 - HKCU\..\Run: [DAEMON Tools Lite] "C:\Program Files (x86)\DAEMON Tools Lite\daemon.exe" -autorun

I now rebootet the computer and haven't yet startet uTorrent, and Hijackthis runned smoothly. Here is the log:

EDIT:

I have now started uTorrent once again and it's working right now. I've looked trough it's file activity in Process Montitor and there is no activity to the file "resume.dat.new" , neither do any other files seem to get FAST IO DISALLOWED

EDIT2: Now it happened again. I was looking at the file activity in Process Monitor just as it happened and this was the last "normal" function call:

14:54:50,7959774 uTorrent.exe 3404 FileSystemControl L:\HD\File.mkv Control: FSCTL_QUERY_ALLOCATED_RANGES

I have looked at the log and this function was called often, but then it always returned SUCCESS. Here it seems to have not returned any value and after that uTorrent just stops reading and writing files.

After that the only file activity is (looping all the time) :

14:55:00,4220589 uTorrent.exe 3404 CreateFile C:\Users\SomeUser\AppData\Roaming\uTorrent\resume.dat.new SUCCESS Desired Access: Generic Read/Write, Disposition: OverwriteIf, Options: Sequential Access, Synchronous IO Non-Alert, Non-Directory File, Attributes: N, ShareMode: None, AllocationSize: 0, OpenResult: Created

14:55:00,4243814 uTorrent.exe 3404 CloseFile C:\Users\SomeUser\AppData\Roaming\uTorrent\resume.dat.old SUCCESS

EDIT: I rebooted the computer once more, started uTorrent and stopped re-check of the torrent with the file that function FileSystemControl was called upon last time when this issue happenned. After a while, exact the same thing happenned, but on another file:

15:27:03,9363372 uTorrent.exe 4436 FileSystemControl L:\HD\File2.mkv Control: FSCTL_QUERY_ALLOCATED_RANGES

After which the uTorrent stopped reading and writing to files.

So it really seems that FileSystemControl doesn't return (or just doesn't return any value ? ) after which this happens. But what does this mean ?
