Hi,<br>
<br>
Occasionally for a day our server will through lots of HDLC errors in
the log and the PRI card with go into alarm.<br>
I have done some searching and this seems to mostly caused from
Hardware incompatibilities / IRQ sharing / Faulty card / Telco problem<br>
<br>
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.<br>
I am trying to find which one is the cause of my problems.<br>
<br>
169: 1399921290 1667044798 1646568485 1544999181 IO-APIC-level
wcte12xp0, wctdm24xxp0<br>
<br>
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?<br>
I take it this is bad?<br>
<br>
We have these cards in our asterisk server:<br>
AEX2451E (Analogue lines)<br>
TE121B (PRI ISDN line)<br>
<br>
Thanks for your help.<br>
<br>
