That's the normal condition if it beleaves no thread is runnable. The question is which of the following aply: 1. an event to a a thread into running state was missed. 2. apache2 deadlocked itself because it makes wrong assumptions about timing, ... 3. something else. If the apache team could exclude case 2 for shure they should be able to tell what went wrong with FreeBSDs implementation. At the beginning of the year I had an apache2 with mod_php4 running on a 4.5-RC1 alpha, but it wasted CPU cycles because one thread was continuously runnable so I had to revert back to apache1. -- B.Walter COSMO-Project http://www.cosmo-project.de [EMAIL PROTECTED] Usergroup [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
