I have Freeswitch running as a SBC in front of several Asterisk machines and without warning one of the Freeswitch processes will use 100% of one of the CPU cores and stop responding to SIP requests. I'm using the latest svn on Centos 5.4 in a xen vm. Basically everything will be fine for about 3-4 hours and then this happens.
