One of the biggest problems with this server is that after an hour or two, Snippets' dispatch.fcgi is using tons of CPU and not serving requests. Despite setting FCGIConfig properly, these processes are not getting killed.
I've written and cronned a Perl script that does a killall -9 on ruby and dispatch.fcgi processes whenever load goes over a certain amount.
Bloocy weird, and highly annoying. It's like dispatch.fcgi is getting caught someplace.
