[Asterisk-Users] Asterisk system lock

[mattf]

Hello,

In the last week I've been getting a lockup about every 2 days. during the
lockup the people that are on the phone can keep talking, but noone can
initiate any kind of call internal or external. I went into the manager
interface and tried a Action: Hangup and Manager gave me a Success message
back only to see that the Zap channel was still active in the "show
channels" screen. 

When I eventually do a "stop now" it takes about 20 seconds before it
finally stops and it says segmentation fault. then I start it back up and
everything works fine.

Does Asterisk need to be stopped and restarted regularly to not crash and
freeze?

Any ideas?

I am using a CVS from October 1st and have the following config:

Digium quad t1 card (400)
P4 2.8GHZ, 2GB RAM, SCSI RAID
RedHat 9
2 T1's hooked up 
50 Grandstream phones set up.

Any help would be greatly appreciated.

Thanks,

MATT---
