I believe I have been experiencing the same issue with the latest stable update, and have narrowed down the problem I have seen to the changes made in revision 5884.  Can you try to svn up -r 5883 (make sure to switch to the current branch if you are using the stable currently) and see if everything works, and if so, svn up -r 5884 to see if the behavior returns?

Hi,

Updated to the latest svn version yesterday, after which I immediately had issues with the poller. Updated from a release about two weeks older. Now I get up/down for different devices, sometimes complete BGP neighbours down on others. Device down alerts on snmp, etc.

I increased the number of poller processes in the crontab and increased snap timeout values etc. However, I still have graphs with large parts missing because of this. Checked poller times, kept an eye on the processes running and logs. Some devices take 120s to poll completely, but all polling is done in about 2 minutes. Still I get these errors, other than the upgrade no changes have been made to firewalls, policies, etc.

Any clues? Do I need to upgrade php?

Show your crontab.
How many memory on observium host.

Send debug output for one device (with long polling time):
./poller.php -d -h some_device > /tmp/debug_poller

(Do not sent this output to list) ;)



Regards,
Rutger
