Today, the server that is running this blog was running out of memory. The problem was there was a subnet range that was hitting different urls on this blog in a rapid succession. I had apache configured so that it was was allowing 150 child threads. This with them memory requirements of LifeType, the box was running out of memory.
After I fixed the apache configuration, I also setup iptables to block requests from that range. In addition, I installed the bwshare apache module. This module will automatically change the response to to a html warning message, which will not require the php script to be run.
