Here are some other questions for you to ponder: - - What appears in the Apache access & error logs just before a freeze occurs? - - Are you using any unusual Apache config file settings or modules? How about for PHP? - - Are all of your installed ports up to date? - - Have you done any Apache or PHP performance tuning using http://httpd.apache.org/docs/2.2/misc/perf-tuning.html or http://phplens.com/lens/php-book/optimizing-debugging-php.php as starting points? - - Have you enabled a PHP log file to record errors, warnings, etc. generated by your application code? Hope that helps, Greg - -- Greg Larkin http://www.FreeBSD.org/ - The Power To Serve http://www.sourcehosting.net/ - Ready. Set.
