CPU maxxed out on Unixware

Hello, We're using apache version 1.3.9 with mod php4 (beta2) on UnixWare (7.1) and are running into a problem with resource allocation. Every 12-16 hours the PHP process (all of our dynamic content is handled by php) appears to take up impossible cpu resources. Top shows it as taking up anywhere from 3000-6000% of cpu resources, the box itself is completely maxxed out and the server no longer processes requests. However, the server DOES reply to requests (error500). Also, the httpd processes take up impossible cpu resources (in the thousands according to top). Eventually we have to stop and start the server. We've traced through all of the code on our site but don't see any problems inline that would cause something like this. Has anyone encountered similar problems? __________________________________________________ Do You Yahoo!? Talk to your friends online with Yahoo! Messenger. http://im.yahoo.com
