I asked the question below about my Apache server stopping serving 
pages.  Since then, the server has continued to stop serving pages 
periodically, and is getting more frequent.  A couple days ago, 
wondering if there could be something competing for the IP port, I 
changed the port from 81 to 8180, and then updated to port forwarding in 
the router.  I really had no reason to believe that port 81 was getting 
any other activity, but it was an easy test.  This did not make any 
difference.  Today I changed the error log level to debug to see if 
anything showed up.  Since that time, the server has stopped three more 
times.  In each case, I remoted into the server, and again was not able 
to access any web pages from a web browser on the server.  As soon as I 
restarted Apache, it started working correctly.  Looking at the error 
logs, there is absolutely nothing to indicate a problem.  Similarly, the 
access log only showed that there was no activity from the time it 
stopped serving pages, until I restarted the server, and then normal 
activity.

I'm running out of ideas.

Anybody else?
