I/O error "not enough space" with plenty of space. qBit 3.1.9

[fusk-l]

I was told to copy the log, so this is everything. Issue has occurred with 3.1.8, 3.2.0a & 3.1.9

This is how it happens.
Notificantion popup saying I/O error "torrent name" reason: not enough space. A few seconds later the exe crashes.

Torrent was done downloading and had seeded for at least 30 min.
torrent was 27gb and drive has 158gb free.

'135641e8312fe54bb9e785084b0433d8452c63ad'.torrent

Is this the failing torrent?
Strange. The log doesn't show your error message...

[sledgehammer999]

PS: Try watching your total/system RAM usage during this period. Note the RAM usage right before the i/o error if you can or right after it occurs.

[fusk-l]

I do not think that is the torrent in question, i only have 1 torrent in the list which must be this one "4b09e57.torrent' resumed."

My highest ram usage that i noticed before the crash from qbittorrent.exe was 1gb, after the crash the exe was gone from task manager, so everything looked normal.

[copywrong]

This happened to me with in 3.8.1 with libtorrent 0.16.12 (magnet links bug) hence my other I/O report.

[fusk-l]

I do not have any experience with magnet, so can't say.
Either do i know how to provoke it.

[sledgehammer999]

@copywrong Does your log contain anything about the I/O error?

I haven't had this problem for a long time.

[ThreePinkApples]

This issue pops up for me once in a while, and I have it now with a torrent. I think the common factor is that I'm seeding a large file. RAM usage reaches 1.9GB ~ and then the I/O error messages starts appearing quite frequently. Looks like it happens when the upload speed reaches 9-10MiB/s, then it calms down a bit to 7-8MiB/s before it starts increasing again. After the first I/O error, qBittorrent freezes if I try to do something in GUI, but as long as I don't touch anything it can run for hours at least, but the error message gets annoying so I usually just stop the torrent.

Torrent size is 63,4GB with 60 files. Has happened on several versions of qBittorent over a few years, runing 3.3.9 now on Windows 10

@aerandir92
If I were you, I would try x64 build and see if the issue persist.

Oh nice, there is one, I'll give it a try

[ThreePinkApples]

@Chocobo1
It worked! RAM peaks at 700MB tops with the 64bit version and not a single I/O error for the 3 hours it's been running

[ngosang]

We are closing all issues related to old qBittorrent versions (qBittorrent < 4.1.0).
Please, update to last release and, if the bug/error/crash is still present, open another issue.
Thank you.
