[users@httpd] Root Apache process disappears
Hello, I am running Apache 2.0.51 and am experiencing some problems.
I have noticed since I installed it a few days ago that my root
process disappears. I have needed to add some Virtual Hosts to it
everyday but when I go to stop and start Apache it cannot stop because
the root Apache process is missing. I look at my httpd.pid file and
see the PID number but that PID is not running anymore. I am forced
to kill all the processes running and the start Apache. Why would my
root process disappear? How can I correct the issue. I compile
Apache with Prefork MPM and SSL. I don't know if it matters but I
have 3 IP's on this machine with about 220 Virtual Hosts and 2 SSL
sites. One IP address is running 2 sites, one IP is running 1 SSL
site, the other IP is running 218 Virtual Hosts and 1 SSL host. A few
of the sites run some old CGI's - one of which is randomly timing
out/failing due to some network issue currently going on. the CGI is
making a call to another server which is having network issues, so the
CGI randomly fails. Would this cause my root process to disappear.
Below is my error log (which doesn't look like too big of a deal)
I am running RedHat Ent.3 - Dual 2.4 Xeon with 1gb of ram.
Thanks,
Nick

Have you checked your process listings to see if there are any
root-owned apache processes? It would be quite unusual for the parent
process to exit without writing something to the error log.

Your MinSpareServers is way too high. Do you really need 50 idle
processes at all times?
Joshua.
