I am not good enough to understand what the system actually complains. I do not think it is a memory problem, could be related to the OS instead. The swap fills although the memory remains free. If you sudo swapoff -a the swap turns into memory, the system turns responsive. sudo dmesg reveals a flood of entries (disregard the martians, these are due to a vpn.)
I do not understand if, and if which, hardware is failing. Memory does nor reveal errors. Sometimes I get a complaint about CPU3 should not be sleeping. This is all I know. Thanks in advance if somebody understands (and maybe can a bit explain) the output. Why does the swap not return to memory once memory is abundantly available?
I just noticed that today (actually yesterday) I had a similar incident.
