UBB.threads PHP Forum Software Community Forums Resources and Customizing Admin Zone Couldn't create child process issue.

so now that apache has been rebuilt, I see the following error in my error log.

PHP Fatal error: PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 730501 bytes) in /home/agentson/public_html/forums/libs/ubbthreads.inc.php on line 826

Any ideas?
