Hi,
Occasionally for a day our server will through lots of HDLC errors in
the log and the PRI card with go into alarm.
I have done some searching and this seems to mostly caused from Hardware
incompatibilities / IRQ sharing / Faulty card / Telco problem
The card will generally run for weeks at a time with no issues and then
it has a bad day... and then good for some weeks or so.
I am trying to find which one is the cause of my problems.
169: 1399921290 1667044798 1646568485 1544999181 IO-APIC-level
wcte12xp0, wctdm24xxp0
Above is the line of my IRQ related to my cards (Full IRQ dump below).
Does the above mean that my two Digium cards share the 169 IRQ?
I take it this is bad?
We have these cards in our asterisk server:
AEX2451E (Analogue lines)
TE121B (PRI ISDN line)
Thanks for your help.
