>Description: I cannot pinpoint any specific time or reason that the server dies. Just every 6 or 7 hours the all the the httpd children will slowly die (within about 10 minutes) until there is only one process left, the one owned by root. I then stop and restart the server using the method described on apaches web page ( kill -TERM `cat /var/run/httpd.pid`). About every three days this method of stopping and restarting the server does not work because it says the port (80) is still in use and there is no /var/run/httpd.pid file and I must reboot the server. I have recompiled httpd recently and it only caused the problem to be worse. I also increased min and max spare servers so as to ensure the server was not getting overloaded. But this problem does not seem to be related to the nubmer of processes running on the system. I'm also attaching a process and netstat report from when the server dies. Don't know if it will help or not, but I hope so. ------------------------- server up, 11 processes, at 18:48:00Monday server up, 11 processes, at 18:50:01Monday server up, 11 processes, at 18:52:00Monday server up, 10 processes, at 18:54:01Monday server up, 10 processes, at 18:56:00Monday server up, 10 processes, at 18:58:01Monday server up, 6 processes, at 19:00:00Monday PS output root 1160 0.0 0.2 848 348 ?
