Hello trm96 and welcome to our forum! Are you using ZFS?
Since I see a lot of
proxmox-backup-proxy processes, could you please post the generated file after executing
top -o %MEM -b -n 1 -w512 > $(hostname)-$(date -Is)-top.txt
Also, could you please check whether you find something relevant in the journal? In other words, please check the output of
journalctl --since="1 day ago" (or, when in doubt, feel free to write the output to a file and post it here).
We have had some similar reports in a
different thread, but that thread is only relevant in case you cannot explain the high memory usage (that is, the memory usage is high even if no processes seem to use that much memory, even if accumulated together). In case you are using ZFS, please check
this post, otherwise
this other post might still be relevant for you. If you would like to try an older kernel version, you can
pin the kernel either temporarily or permanently.
