recheck at startup

[kvarga]

I'm downloading 2 torrents (42.2GB and 59.7GB). If i dont shut down the µTorrent manually before Windows, it checks the files at next startup. I'm using the v1.6 build 474.

Sounds like your system shutdown isn't giving uT a clean close.

[kvarga]

With the previous version (v1.5) it was good.

Oh crap those are huge torrents... Um, everything else works fine (green light and all), right? Have you tried disabling UPnP and/or DHT? It's a major cause for a bunch of other problems, and I'm not sure if it's relevant in your case, but it might be worth a try.

[kvarga]

Everything seems green/OK. DHT and UPNP are disabled by default. There are 120-150 connections/torrent.. that can be a problem? Shall I reduce the number of connections?

[dAbReAkA]

same thing for me.. Ultima that has nothing to do with the number of connections/green lights and stuff like that..

[Ultima]

My point in asking that was to check if a firewall was causing problems. And some people have crappy network cards/drivers that can't handle too many connections as well, and hang Windows instead at shutdown.

check out first post:

his problem is that utorrent checks the files downloaded during the last session everytime if the program is not closed correctly..

he has to close utorrent and then shutdown, so that it is closed properly and not terminated causing uT to check the files on next startup

I think you cannot do much about this issue. uTorrent is not very fast in closing down and Windows probably kills the process before it can shut down properly (especially if you have certain "tweaks" in place). I'm not sure what uTorrent does when closing down and why it takes a little longer than most other apps though...

[Game90]

maybe its because of the new cache? from what i observed ut 1.6 takes more time to write cache to disk than ut 1.5...maybe it couldnt do it in time.

[dAbReAkA]

no, it depends on the torrents it has to announce stopped to trackers.. try removing ur torrents and u'll see that it exits immediately..

currently, it announces them as stopped and if no tracker response is given by the 15th second it terminates

what about a new advanvec option for the time it waits before it terminates with a default value of 15000 (ms)?

or uT could probably read windows's registry and find what the time before windows terminates the processes after sending them the exit signal is and adjust itself properly (terminating in the time set - 1000 ms)

[Klaus_1250]

@Game90: I doubt that, the average HD writes with at least 10MB/s, so you would need a huge cache to slow it down that much.

@dAbRaAKA: 1000ms is way too short. It would also think that there is a reasonable time defined in the BT-specs. 15s doesn't all that bad. Last, I think it also takes more time than just a second to close all TCP-connections gracefully.

[dAbReAkA]

why should it follow the BT-specs

it works as follows:

1. when shutdown/restart is activated, the OS sends uT the exit signal

2. the OS waits (i think 15s by default) and if there are still running processes, it kills them (uT may not be able to save its setting if it gets killed)

3. it shuts down

i suggest it to work like that:

1. get the maximum time before terminating (either by the windows waits minus 1 second or something like that or by a variable in the settings) - the first one is better

2. try to close the TCP-connections gracefully for the time it has and if the maximum time before terminating comes and not all connections are closed, terminate (saving settings, etc..)

currently it will get killed without saving the settings, resume data, and so on, and it will have to recheck the torrents to see the progress

Klaus_1250 i didnt say 1000ms, but the time the OS waits before it kills the processes in miliseconds minus 1000 or 500 or whatever..

[Klaus_1250]

Because specs are there for a reason. But, I looked up the BT-specs, but couldn't find any mention of time-outs? Odd.

The problem is that there are tweaks floating around with unreasonable value's for killing off processes. You can read out the value for them in the registry, but with bad luck, only to find that you may never be able close the program gracefully in the given period.

As for the (TCP) connections. Not closing them properly can create a whole range of problems, if I remember the early days of p2p correctly.

In any case, it is worth investigating why uTorrent now takes longer to close. Perhaps the shutdown-sequence can be streamlined or made more parallel, or an advanced aggresive option for instance, discarding data in transit / the cache.

[dAbReAkA]

what do u prefer?

uT terminating at the 14th second, not closing all the connections gracefully, but saving the settings properly, thus avoiding hashchecking of torrents (in the thread-creator's case 40-50 GB.. do u know how much time it takes to check all that data?)

or

uT being killed at the 15th second, not closing all the connections gracefully and not saving the settings and resume data, so that it needs to check the 50 GB torrents at startup

as i said, uT should try to close them properly, but if it seems to fail to do that before the time of it getting killed approaches, it should terminate wisely instead of being killed

and it could read that registry data to see when is it expected to be killed so that it could wisely exit just a bit before that.. if it is supposed to be killed at the 3rd second for example, it could try to close the connections and if it fails to by the 2nd second (which would most probably happen) it should have a second or as much time it needs to exit

One of thr two torrents finished. Now I'm downloading only one 59.7GB. The problem disappeared.
