Re: Apache stops serving pages

[Jim Walls <jim@xxxxxxxxx>]

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?

I have Apache 2.4.12 running on a 64 bit Windows Server 2012 R2 installation that periodically just stops serving web pages.  Usually it will start working after an hour or two, or if I'm in a position to remote into the server I can restart the service using the Apache Service Monitor, and normally get it to start without waiting.  There is absolutely nothing in the error or access logs.  I have not seen anything that seems to relate in the Windows logs either.  I thought it might be having a firewall (either Windows or router), but last time it stopped, while remoted into the server, I brought up Firefox and tried to access a web page or two.  I get the browser error that the web server is not responding (or something along that line).  That should eliminate the router, or Windows firewall I would think.  As soon as I restart the Apache service, both Firefox on the server and on a remote computer are able to access pages.

 

The server gets restarted every Friday afternoon, and last Friday Apache stopped within a couple hours.    Problem happen anywhere from a few hours to several days apart.  This is a very plain vanilla server that is serving three Virtual Hosts (all are affected at the same time), with no dynamic content - just plain old html

 

Any good ideas of a cause or where to start looking?
