[asterisk-dev] Asterisk zap channels death

[Anton]

I'm experiencing a ZAP channels problem, 
after a while of operation (2-3 days, sometimes up to a 
week) my ZAP phones (channel bank connected) just dying, 
becoming silent. No any console complaints, not suspicious 
debug messages. Just all of the ZAP lines became silent. 
Asterisk restart gives nothing. Only full drivers and 
ZAPTEL reload restores the operation. I Use SANGOMA E1/T1 
card A102. BTW, this behavior is exist in both 1.2 and 1.4 
versions with slight difference - in 1.4 ALL channels 
dying. In 1.2 only some channels may die. 
Looks like a kind of deadlock and if anyone can give a clue 
how to debug that behavior that will help a lot.

Regards,
Anton.
