[Asterisk-Users] Zaptel/PRI problem

Here is what we get:

Apr 10 18:10:34 WARNING[-1179604048]: chan_zap.c:6026 zt_pri_error:
PRI: Read on 24 failed: Unknown error 500
Apr 10 18:10:34 NOTICE[-1179604048]: chan_zap.c:6740 pri_dchannel:  PRI
got event: 8 on span 1

We were getting around 5 messages per second. I turned off the usb
interface in the bios and now the messages have greatly reduced in
number e.g. a few messages each minute.

We only see the errors on the console. What frequency of messages were
you getting? Sound dropping in voice calls may be related to something
else.

Tan,
Scary ...
What we used to see was quite few (and sporadic) notices and warnings in
the /var/log/messages file reporting PRI trouble.  Especially event 6
and event 8 if I recall.  These notices and warnings have disappeared
since we resolved the interrupt issue.  Because the implementation is an
office PBX, and the office had light call volume Friday afternoon and
closed for the weekend, I do NOT know if users might still experience
sound dropping on voice calls.  
My question to you: when you state 'similar problems', you
mean dropping voice (sound), or having spurious PRI events,
or both.
Cheers,
WW
