I have a template in my control panel (technically a plugin, but it's just one template) which is running out of memory:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 78 bytes) in /var/sites/t/thames-arbitrators.org.uk/craft/app/helpers/ModelHelper.php on line 101

In my local dev site, the profiler is giving me the following info:

  • Time 10.66053s
  • Memory: 127,544Kb
  • Total Queries: 381

Is there anything I can do to alleviate this? I've seen the answer to 'PHP Fatal error: Allowed memory size of X bytes exhausted' but there are only two conditionals in this template, it's almost certainly down to the fact that I need to return several hundred entries.

I don't mind posting my template here but there's a big table in it so it's going to make the page super long - let me know which bits you need.

  • Hi, we have the same issue on a entries template in the admin. Looks like the UserSessionService::getAuthTimeout() is using an abnormal amount of requests. Need a patch ASAP!

  • @DanG Your issue is most likely different and should be addressed in the next release.

If your plugin is pulling in a lot of data, then most likely you're just bumping into your php.ini file's memory_limit setting. Try bumping that up to 256M and see if that helps.

  • Thanks Brad, I'll have to talk to the host and see if I can increase it. 134mb is already a hell of a lot though and the site's only been live for a month. It's going to increase by another hundred entries every month. Would pagination stop the overhead? Sep 25, 2014 at 8:12
  • Maybe? Caching would likely be the first place to look, but it's hard to tell without seeing how your data is organized and your plugin code and what it's doing.

  • I tried caching the data to reduce the overhead but it was causing issues - you advised me that caching was never designed to be used inside the control panel :) Sep 25, 2014 at 15:04
  • The {% cache %} tag wasn't, but there are other ways of caching
