out of options via the FAQ :(

I frequently encounter this error:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 2057794 bytes) in /home/napafter/public_html/ra2/sources/caches_filesystem.php on line 91

Clearing the cache will resolve it for a while, but it will eventually return.  The error can be limited to a specific browser (for example, IE users encounter the error while Chrome users don't).  

I am using the recommended .htaccess file, and as far as I can tell, it appears to be setting the memory limit to 128M.  Any advice to next steps would be appreciated.

We recently got a support ticket on this too. It was failing at a lower memory limit for them, but this is the answer…

Hi,

You seem to have the 'use_mem_cache' option enabled in the base
configuration (the info.php file, editable via the config_editor.php
script). You should only do this on a server with a PHP memory cache
available (e.g. apc), as otherwise it will need to use a filesystem memory
cache which will probably hurt performance more than helping it. Much older
versions (maybe version 5, but I can't remember that far back to be honest)
had it on by default but that was changed.

Was I helpful?
  • If not, please let us know how we can do better (please try and propose any bigger ideas in such a way that they are fundable and scalable).
  • If so, please let others know about ocPortal whenever you see the opportunity.
  • If my reply is too Vulcan or expressed too much in business-strategy terms, and not particularly personal, I apologise. As a company & project maintainer, time is very limited to me, so usually when I write a reply I try and make it generic advice to all readers. I'm also naturally a joined-up thinker, so I always express my thoughts in combined business and technical terms. I recognise not everyone likes that, don't let my Vulcan-thinking stop you enjoying ocPortal on fun personal projects.
  • If my response can inspire a community tutorial, that's a great way of giving back to the project as a user.

Very good.  I changed that setting and I will see how it goes.

Thanks so much!
