> Segfault occurs whether system is idle or is in-use. it will crash within a day or two even if 0 calls are made on it.  running under safe_asterisk, results in multiple crashes within a few minutes until eventually system ends up in a MUTEX lock. over 3 gigs of RAM available and plenty of disk space at time of first crash. Possibly related to the 96 port gateway producing 96 SIP registrations all at once?
