Markus, thanks for your input. However the system went from 0.16.X -> 0.17.5.X and is behaving badly. It might be as you say but before I upgrade PHP any more ideas? System have 39 devices to poll. Have four CPUs and 6Gb RAM. It starts to behave badly directly from the beginning when enabling the CRON job.

My guess is that your system is not fast enough to poll all your devices in 5min, creating new poller processes before the old ones are done. You should start by upgrading your PHP to version 7 as this is much faster, if the problem still persists then post a screenshot of the /pollerlog-page in the Observium GUI please.

2017-06-29 19:48 GMT+02:00 John Klasa <John.Klasa@itiviti.commailto:John.Klasa@itiviti.com>: Hi I’ve upgraded to this version: ./discovery.php -V Observium 17.5.8580
It seemed to be a great update but then MySQL died and I found this in the logs:
[2017/06/29 15:05:20 +0200] poller-wrapper.py(29309): /opt/observium/poller-wrapper.py: URGENT: poller-wrapper not started because already running 34 processes, load average (5min) 37.17
And it kept increasing upton load over 70 where I killed all python, CROND and for some reason A LOT of ps processes. An example of processes below.
26133 ? D 0:00 ps -ww -o ppid,uid,args -p 23434 26331 ? R 0:00 ps -ww -o ppid,uid,args -p 2981 26354 ? R 0:00 ps -ww -o ppid,uid,args -p 10439 26355 ? R 0:00 ps -ww -o ppid,uid,args -p 11755 26356 ?

Anyone know whats going on? I see this when I try to run the debug output
Your PHP version is too old (5.4.16), | | functionality may be broken. Please update your PHP! | | Currently recommended version(s): 7.0.x or 5.6.x
I guess I should upgrade PHP first.
