I’ve been having an issue on my main workstation (and only this machine) ever since the update to kernel 5.3.
No current patches to the kernel have fixed it, and nether did upgrading from 30 to 31. The issue did not occur on any kernel 5.2 releases, and doesn’t seem to be related to any userland applications.
I have tried everything to diagnose and resolve the issue but I cannot fine any useful information.
The issue is simple. After booting my system, all I have to do is wait, and my system will slowly consume all of my 16GB of RAM until the entire system starts to thrash from swapping and become unusable.
Application memory usage will be nominal, and no buffers will be allocated as all the memory is in use. The memory just disappears over the course of about 24 hours, with the system reporting it all being used with no indication of what is using it. ‘meminfo’ and ‘slabinfo’ both show little change over what is reported.
Rebooting is the only way to alleviate the issue, but is, in itself, an issue.
Anyone that can help, or that knows where to look, please give me some direction here.
I’m not even sure what info to give at this point. Everything seems normal, other than I have no free memory.
I can’t even go back to 5.2 now, as it’s no longer available in the repos for 31.
