Hello list,
I am having problems with my server, this box has been running OBSD
for the last 3/4 years without problems. A few months ago the box
begun to experience lockups once time at week during peak hours, now
the lockup is several times a week.
The last messages in the system logs are "/bsd: proc: table is full", I
think that the load (which isn't very high) is stressing the machine and
finally hangs the server. If I don't get it wrong a properly configurated
system doesn't fail under stress.
I tunned some system variables but the problem persist so I am going to
ask for advice about how I can monitor to discover the culprit.
does anyone knows that system parameters I must monitor?
below I attach the relevant files and dmesg.
Thank you.
