My members have started reporting to me today that they are receiving fatal errors when searching for New Posts or Today's Posts:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 524288 bytes) in /www/scienceforums.net/html/forum/includes/functions.php on line 243
Our memory limit is 64MB, as you can see, and somehow vB is still exceeding that limit. My investigation shows that the line above is in the function vbchop() in the midst of a regular expression. I'm not entirely sure what I can do to fix it, since out-of-memory errors can't be caught by a custom error handler so you can get a backtrace.
Is this a known problem with a known solution, or should I just up the memory limit to 128MB? (Surely 64MB is enough for any script...)
