PHP Fatal error: Allowed memory size exhausted

[Mechanix]

Hi,

Zabbix 3.2.3

I´m receiving following error when on the graphs page all hosts are selected:

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes) in /usr/share/zabbix/include/classes/macros/CMacrosResolver.php on line 1069, referer: https://<someurl>:9443/charts.php?fullscreen=0&groupid=0&hostid=10215&graphid=3268

I have tried to increase the memory_limit in /etc/httpd/conf.d/zabbix.conf but it didn´t fix the issue.

Any thoughts? Thank you

Hello!

You can also try to adjust the max_execution_time PHP setting to a higher value keeping the changes done to memory_limit. What exact amount of RAM do you have specified there?

I got 16GB of RAM but I managed to solve this. Actually there were multiple php.ini files. Edited the right one and now it works, thank you

Could you please let me know exactly what you edited? I have this error and have edited a couple of files where I found entries, but still no joy.

Hi,

I created a info.php file in /usr/share/zabbix with following content:

<?php
  phpinfo();
?>

now, point your browser to http://<your-zabbix-server/info.php

you should see a line Loaded Configuration File

Thanks for your suggestion, however the info.php pointed me to the file /etc/php5/apache2/php.ini as the loaded config file. I looked in this file and I have already increased the memory limit to 512M, but still I get the error message. See below:

; Maximum amount of memory a script may consume (128MB)
; http://php.net/memory-limit
memory_limit = 512M

Ok, so an update on this...

Basically went through and grepped the whole appliance for the string "memory_limit". Found some other files and updated these and after restart, the Latest Data page now loads.

However, it takes an obscene amount of time to load. Either loading the latest data page, or performing a search, takes around 20seconds to return results, even if the result is only one item. All other pages load within a second.

We are running the Zabbix appliance on 3.0.9, and relatively small deployment at present - monitoring 140 hosts.

Hi,

so basically the php variable can only be overwritten in

/etc/httpd/conf.d/zabbix.conf

Check that file.


Cheers

*edit* just to make sure: you restarted the webserver after the change right?

That´s strange. Are you able to update the zabbix server to the latest version?

BTW: how much RAM does the server have?
