Ktorrent locking the system
seems to be a ktorrent problem. But also may be because of kernel, don't really know.
All works, but at some time X stops responding, mouse stops moving and I see the activity of hard disk (hdd led is on).
In /var/log/messages the following appears many times

It seems, that the memory and swap are fully filled.
After some time (10-20 minutes) X restarts and everything goes ok.
Maybe it's kernel's problem, but this lines always appear with "ktorrent D f38bbb5c 0 10352 1 0x00000000" before.
I suppose, I'd file a bug to ktorrent or kernel, but not sure.
What should I better do?

I'd log a bug. If you rename the ktorrent config folder(s) then rerun it (giving vanilla settings) does it run ok?
Evgeny Brazgin (xapienz) said : | #2 |
ktorrent runs ok.
The bug isn't reproducible always. I even don't know what should happen before appearing.
It may have gone some days of ktorrent running before freezing.
I'd log a bug
Can you help with this problem?
Provide an answer of your own, or ask Evgeny Brazgin for more information if necessary.
