asterisk users - Feb 2005 - Zap Channels Disappear???

Problem: Zap Channels Disappear @ random intervals. (Channels have
disappeared on both gateways twice this week).

 

My Setup:

 

I have 2 Dell 1850 Power Edge Servers - Configured as.

 

P4 2.8Ghz

512 ECC Memory

SCSI Array (2 Drives Mirror)

 

Configuration is really simple the boxes are setup as PSTN termination
gateways: (SIP/ZAP) - We are running a SER/Asterisk Hybrid.

 

My asterisk and libpri are built from the lastest 1.0 stable branch
(2/14/05) my zaptel is built from the latest CVS head (2/18/05). Linux RHEL 3.0 

 

The only compile time change I made to zconfig.h is enable MMX for the
drivers.

 

The Cards are 4 port Tormenta cards from envarion.

 

Gateways are very busy (13000 / 3 minute calls a day)

 

Any advice or opinions welcome!

 

Thanks in advance!

 

Chris.

Maybe this is a problem with enabling MMX in recent builds? OK, my
problem isn't identical: instead of random it's consistantly on
reboot; instead of RHEL I've got CentOS 3.4 (using *@home); and my
error is "can't load chan_zap.so"

I'm going to go rebuild zaptel without MMX enabled and see if I still
have this problem.
