PHP Fatal error

[J.R. Rogers]

I've been getting several Fatal PHP errors showing up in my Apache log and they almost always precipitate the vB 'white screen of death' problem with my forum, which usually requires a restart of Apache and MySQL to fix. Here's the error:

[client 207.69.137.34] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 35 bytes) in /*****/forums/search.php on line 1011, referer: http://*******/forums/search.php?do=process


This almost always happens with search.php but sometimes even happens with index.php or other scripts. I keep increasing the memory_limit in etc/php.ini but the error never goes away.

memory_limit = 32M ; Maximum amount of memory a script may consume

Any ideas? Thanks!

You need to increase that setting to at least 48M.

You will also need to restart Apache for that change to take affect.

[J.R. Rogers]

Thanks, Steve. Will give that a try.

[J.R. Rogers]

...And the errors continue.

Any more ideas?

I don't see any reason for search to take up this much memory. Have you installed any add-ons?

You also might want to reduce this number:

Admin CP -> vBulletin Options -> Message Searching Options -> Maximum Search Results to Return

Thanks, Steve. Okay, I reduced the search results to 300 from 500. I'll see if this helps. The only add-ons I have installed are "Who has visited today", "Guest Tracking", and "Mini Navbar".

I've got a couple sites where it needs to be in the 128-160MB range in order to not return white pages on 1000 results. That's one of the reasons why I switched to the Sphinx search.

I'm getting this error when I delete a post.

The reason I posted this is because it's the same, but brought on by a different cause. What can I do to resolve this?

It's not really a different cause; you're still running out of memory due to a complex operation. 8MB is really too small, particularly if you're running PHP 5.2.0 or newer (where the default is now 16MB).

Just start raising the memory limit until those errors go away.
