I have experienced something similar but I haven't had time to reproduce it.
I observed many times in January this year and the way It happened was: ~100 requests per second php-fcgi with 10 workers php-fcgi suddenly hangs and then the CPU usage on cherokee worker jupmps to ~790% (on a dual 4-core server, 800% is maximum possible CPU usage) I don't know if this has been fixed, but I was planning to reproduce it with an openx with enough load and running 10 instances of a php application that sleeps for more than 120 seconds until the PHP seems to hang. I got into a very demanding projecto so I have not had time to run this experiment, but I will try it on March.
