Running Apache on Low Resources
These are some notes about running Apache2 on an Ubuntu virtual machine for development purposes. In most cases these notes apply as well to typical low-resource environments.
Apache2 RAM Segfault
When running a default Ubuntu install of Apache you may find Apache keeps connections alive for a very long time
and begins to devour RAM until it segfaults and freezes the virtual machine. The following changes to the MPM prefork configuration in apache2.conf should prevent this from happening. These settings may not be suitable for production environments.
StartServers 2 MinSpareServers 2 MaxSpareServers 5 ServerLimit 20 MaxClients 20 MaxRequestsPerChild 10000
If your development machine is not operating under heavy CPU load, you can set ''[=KeepAlive=] Off'' in ''apache2.conf''. This may cause a dramatic spike in CPU use per page load, but this spike should drop off immediately after the Apache has finished handling the request.
# apache2.conf KeepAlive Off
