I can not start another (5th) instances of Apache. Below is the error message from /var/www/logs/error_log:
[Thu Dec 1 01:51:19 2005] [error] mod_ssl: Parent process could not create private SSLMutex semaphore (System error follows) [Thu Dec 1 01:51:19 2005] [error] System: No space left on device (errno: 28) I tried to stop all the instances of Apache and ipcs reported no left-over semaphores . Then I can start only 4 instances. The 5th one always gives the above error message. How can I fix that? Thanks, Zoong
