Hi! All, We have an Apache-2.0.54 instance running on a SUN box of Solaris 8, it runs as worker MPM. I tried to increase its ThreadsPerChild for our env requirement. Seems it's OK to push the limit to 350 ThreadsPerChild but failed it's higher than 400. The processes died automatically and the error_log had the following errors, [Thu Aug 24 12:27:16 2006] [notice] Apache configured -- resuming normal operations [Thu Aug 24 12:27:16 2006] [alert] (11)Resource temporarily unavailable: apr_thread_create: unable to create worker thread [Thu Aug 24 12:27:26 2006] [alert] Child 10446 returned a Fatal error... Apache is exiting! Can someone tell me where this hard limit is set in source code, and can I change it, or if there is a way to push the ThreadsPerChild limit higher?
This means the pthread_create call is failing on your system. This could be because you are exceeding PTHREAD_THREADS_MAX. But I don't remember enough Solaris 8 stuff to know. The important thing is that there isn't really anything that can be done in apache about this, other than lowering ThreasPerChild. There may be an operating system config that can help.
