Since yesterday I'm encountering VPS performance problem (I've already posted a ticket about that but looking for some more technical explanation than just fix). Periodically MySQL server doesn't respond which throws errors on some of my sites and I can't login through sftp.
After looking into VPS Virtuozzo panel I found out that one of resources named: 'othersockbuf' goes quite often into black zone, and because of that (to my understanding) some of processes on VPS are refused to run.
All I know about othersockbuf resource is what I read from Virtuozzo manual:
Quote:
|
The total size of UNIX-domain socket buffers, UDP, and other datagram protocol send buffers
|
which tells me basically nothing
There's no word on how can I check which processes uses that resource and how can I eventually adjust its setting like lifting soft limit and lowering limit of other resource or simply speaking how can I fix the issue.
Do anyone has better understanding of what's going on? If it's general RAM memory shortage I'd be quite surprised as I didn't changed much on server lately and there's surely no more load than it was before.
