Hi,
I have a bit of a strange situation occurring with opsview-web (Community
Edition Version: 3.11.1)
This was last upgraded in Feb and has been running well since.
We are running it as a clustered service using heartbeat/pacemaker if that
makes any difference.
Yesterday we needed to restart the machine.
After that, opsview-web was using a lot of resources (100% CPU on an 8 core
box!),
and was (what looked like), continually recycling this script:
perl script/opsview_web_server.pl -f --background --pidfile
/var/run/opsview/opsview-web.pid --host 0.0.0.0
i.e. starting up multiple copies and then stopping them, but always quite a few
running.
I managed to work out that if this command was run manually from a shell,
it is fine (normal CPU and no multiple copies starting, etc).
However, starting opsview-web using the init script results in the bad
behaviour.
Theopsview-web log with DEBUG enabled doesnt give any useful info.
I found some similar issues on the forums and added this to opsview.conf:
$use_prefork = 1;
That seems to have stabilized the machine, theopsview_web_server.pl processes
(although a lot of them now), seem to be fairly static.
However, I can see the CPU slowly creeping up again, heading towards 100%.

I just cant work out why this would suddenly start happening now.
It has been running fine for several months.
Any ideas?
Thanks.
Regards,
Andy.
