This is something new, Apache is running fine as server on a Windows Server 2012. There is plenty of RAM and CPU and this is the only thing this server does, is an Apache server.

I can restart the service and it will run fine for a little bit then stop serving pages on all sites. I have messed with the worker threads to find a fine line but still having issues.

Currently settings in httpd-mpm.conf file

<IfModule mpm_prefork_module>
    StartServers             10
    MinSpareServers          10
    MaxSpareServers         20
    MaxRequestWorkers      250
    MaxConnectionsPerChild   3000

At this point I am not sure what is going on and have tried several suggestions from various websites.

Specs of Server: Windows 2012 R2 VM 2 GB of RAM 1 GB available Running on an SSD storage

This server connects to a MySQL database on the same network as well, there is not latency between the servers.

When you have hangs, slow traffic and/or when having in your log entries like Asynchronous AcceptEx failed. You can try the following settings:

AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off

IfModule mpm_prefork_module

prefork is only on linux. That settings will never be applied. Wink

Most used WinNT ( Windows) MPM settings are

<IfModule mpm_winnt_module>
    ThreadsPerChild      150
    MaxConnectionsPerChild    0
