Forum Database errors being reported since upgrade to 4.2.0
 

Several of my members have reported a database error randomly appearing since updating our forums to 4.2.0 a couple of weeks ago.

Error is:

Quote:
Fatal error: Allowed memory size of 18874368 bytes exhausted (tried to allocate 10485742 bytes) in removedpathname/functions_threadedmode.php on line 23

Always the same script, functions_threadedmode.php, reporting its exhausted the allowed memory size and even if i edit the php.ini file and increase this limit, the error just comes back with higher number!

Any other bright idea's?
