Re: System is slow, CPU usage skyhigh

Have you seen any similar problems with other installations, and have any tips to prevent this from happening again in the future? We saw something like this in a few mysql tables, but this is the first time we've seen it in a postgresql table. We did some adjustments to our db maintenance script, ...

Re: System is slow, CPU usage skyhigh

Running dbmaint on our server produces the same kind of output as i copied into my post of january 6. No mention of MIBs in the output, so the problem doesn't seem to be related to that. There is a bit of disk i/o on the system, but since neither 'top' nor 'vmstat' reports any waiting on i/o (aside ...

Re: System is slow, CPU usage skyhigh

'ps aux|grep dbmaint' gave no output aside from the grep itself, so no dbmaint.php processes were running. running the script however gave a bit more output: # /usr/local/nagiosxi/cron/dbmaint.php CLEANING ndoutils TABLE 'externalcommands'... SQL: DELETE FROM nagios_externalcommands WHERE entry_time...

Re: System is slow, CPU usage skyhigh

All that's in the logs are two separate error messages, repeated to make a filesize of about 20kb per day. The error messages are "LOG: could not receive data from client: Connection reset by peer" and "LOG: unexpected EOF on client connection" with the latter being more frequent...

Re: System is slow, CPU usage skyhigh

We are still experiencing crazy loads from postmaster/postgres. Do you have any further ideas what may be the problem or cause?

Here's a screenshot of a 'top' from the machine, sorted by %CPU, in case you have use for it.

Re: System is slow, CPU usage skyhigh

We have now updated to the latest version, 2009R1.4. The upgrade itself is working fine, but postmaster/postgre is still eating up a lot of CPU and slowing the whole system down. A screenshot from a few minutes ago of 'top', sorted by processor usage, showed 13 postmaster processes each using from 1...

Re: System is slow, CPU usage skyhigh

It's been running with the postgresql changes for a few days now, and i don't notice change in postmaster's cpu usage.
If there's been any changes, then they are minimal.
