PHP Fatal error: PHP Fatal error: Maximum execution time of 59 seconds exceeded

[smileymind]

Having two pollers running at the same time is almost certainly bad.

I only had a brief look at the map, and it seems pretty normal, even if it's quite big. I noticed there is no rrd_use_poller_output in it though - did you do that in the map settings? What was the render time for the map before you did it? (grep "run complete" cacti.log should tell you)

Hi Howie,
I already enabled rrd_use_poller_ouput, before and after enable it seems the same around ~32 seconds. Please see log in attached. Right now it seems quite better as it stucks 1 in 10 polling, so we can say 1% error in 10 polling. Thanks.

In /etc/php/versionNumber/apache/php.ini

; Maximum execution time of each script, in seconds
; http://php.net/max-execution-time
; Note: This directive is hardcoded to 0 for the CLI SAPI
max_execution_time = 30

; Maximum amount of time each script may spend parsing request data. It's a good
; idea to limit this time on productions servers in order to eliminate unexpectedly
; long running scripts.
; Note: This directive is hardcoded to -1 for the CLI SAPI
; Default Value: -1 (Unlimited)
; Development Value: 60 (60 seconds)
; Production Value: 60 (60 seconds)
; http://php.net/max-input-time
max_input_time = 60

And the same parameter in /etc/php/versionNumber/cli/php.ini

Try to change, may be it will help you.

Hi,
I already tried that but it still shows error sometime and map freeze until next polling run complete.

Thank you,

Now all issues have gone away just simple change on SNMP waiting response time out, set the max waiting 300ms only so my polling will shorter than one minute and the weathermap also load faster.

Thank you all for your support.

If that has reduced your polling time, then surely you have data that is not being collected now? (that is, it is hitting that new timeout)

[phalek]

If reducing the timeout solves your problem, then you should check which devices are actualy not repsonding to SNMP requests. A previous post already showed that you're hitting the 60 Sec polling time, so you are missing data before changing the timeout already.

Thry sorting the devices by response time and go through each of these to check their SNMP reachability. Also check if slightly increasing the MAX OIDs to something higher then 10 may help resolving polling times. I think 0.8.8h should allow doing this on a by-device basis.

There's a plugin available which may help you for the getting the best MAXOID setting per device: https://github.com/patrickscottbest/hammerOID
