µTorrent crashes when disk unresponsiveness leads to memory overflow

[miniyou]

Cannot find a thread about my particular problem.

I've had this problem for a few months, and I cannot connect it to any specific event.

Description:

µTorrent runs normally for an arbitrary amount of time, ranging from an hour to a few days. Then, for some reason, there are no disk writes whatsoever. While this happens, the cache fills up and one of two things happen:

1) The download speed is so high that the cache fills up completely and the program ceases to respond. I can still see how the window looked when it crashed, and I can see that the cache is full and there have been no disk writes for a time.

2) The download speed is low enough to wait for the disk to respond again (i.e. the cache can take it all). When the disk responds, it quickly writes a lot of data and come back on track again. Continues to run normally again for a while.

Screenshots:

The disk unresponsiveness seems to be like 5-10 minutes or so looking at the images.

What I've tried so far:

I have tried reinstalling, resetting all settings, upgrading µTorrent. Also changing physical disk with content, but it's the same HDD models in the same computer and OS.

Also fiddling with lots of advanced settings (all kinds of disk and cache settings).

Also, I have tried activating and deactivating Window's write cache to the disk (in Window's settings) with every combination of settings in µTorrent.

Thing is, I believe µTorrent cannot control nor predict when the disk problems will occur. Possible solution would be that it could detect when the cache is filling up without being written to disk, and just wait out the problem. At the moment I use a workaround - as you can see on the screenshots - I simply cap the download speed to a very low speed (around 1 MiB/s). This is undesirable.
