Back from Vacation, CPU in Permanent Spike

A nice welcome back from vacation. First thing I check this morning is the orca graphs and discover that the CPU was spiked on our primary webserver for the past 48 hours.

A quick ps -Af reveals that sometime on Saturday two requests came in for PDFs and attempts to generate them with FOP went out of control. After gathering a few pieces of data I killed the two FOP processes and we're back to normal.

We have yet to find which of the 340 PDF requests on Saturday sent the process running wild, ps will give us 82 characters of the command line request, which is too short to figure out the important details of the request.
