We have recently install an asterisk solution with about 60 physical extensions. While the system is running it runs reasonably well (Still have a few teething problems) but twice now they have experienced a degradation in voice quality and dropped calls and then finally asterisk completely crashes out. Restarting asterisk will work for a little while and it will crash again, each time less time will pass before a crash out. The first time I didn't have much logging so I didn't get anything to work with. I have since turned on debugging and following is the logs from the time of the last crash. Can anyone point out where the problem may lay, suggested updates or changes?

Once the system becomes unstable the only way to get it up again is to shutdown (not restart) pull the power and USB on the Xorcom Bri 4 devices. Then plug them back in and start the system up. If the power and USB is not disconnected a the devices may look like they are working fine but zaptel will not start stating that it can not find span ** what ever it happens to fail on. We are running the following versions Asterisk - Asterisk 1.2.18-BRIstuffed-0.3.0-PRE-1y-g Zaptel - zaptel-1.2.18 XPP - version: trunk-r3965 srcversion: 723B8A27A7E9750BB039D00 If you need any more information please let me know.
