Comment 22 for bug 1852001

Still this bugs haunts me every day.

kernel 5.3.0-29-generic still affected.

whenever swap is enabled, the system is almost unusable when cache grows too large with time. as already told, this is by far worse than the infamous linux swap trashing.

while this can be worked around easily, I am still logged out without any warning randomly about every day, killing all active programs.
This seems a bit more likely when I have Windows Virtualboxes running, that have more than one processor core assigned. I already updated VB-Client, VB-Settings...

my assumption: this is some threading issue. maybe wrong priority of some graphics stuff, maybe too many semaphores in swap-in code... I don't know.

This problem annoys me for almost a year now. I give up.
My last try is making Virtualbox work with the testing kernels.
If this doesn't work I will try some other distribution.
