Fatal error: Allowed memory size of 33554432 bytes exhausted

[MarkPW]

I'm running Litespeed 2-CPU Enterprise edition (v3.3.11) on Linux x86 4GB RAM (web server only) and my users are reporting the following error on my forums:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 16783 bytes) in /path/to/mysite/forum/showthread.php on line 1265

Is it a case of adjusting memory_limit in php.ini or is there a setting within the Litespeed admin that I can amend? Also, what would be the suggested memory limit for a site that has around 2800 users online peak, 2200 average (15 min timeout).

Your help would be appreciated.

You can increase both limits in php.ini and LSWS web console. The memory used for opcode cache counted towards that limit.
