[asterisk-users] TE412P (T1/E1+DSP) digium card cause server crash

Hi all

I have a server that has two TE412P (T1/E1+DSP) cards installed. One of them
configured as an E1 PRI connected to PSTN and another one configured as a T1
E&M connected to Avaya PBX. Each card only uses two ports, so there are 2 E1
lines and 2 T1 lines connecting to this server. The purpose of this server
is as a TDM trunk gateway that gets call from E1/T1 and then forward to an
IP-PBX via SIP, or gets call from an IP-PBX and forward to E1/T1 via SIP.

Unfortunately, the server crashed (serve dead/card hanged) often when
traffic is high (E1 + T1 about 50~70 active channels). Is it zaptel driver
issue? The server loading actually is not so high before crash.

I've been investigating this issue for weeks and I'm totally out of ideas,
so any help or suggestions anyone could provide would be greatly
appreciated…

Best regards
Ian
