[Asterisk-Users] PRI issues with TE410P

Hello Azher-

I have a similar setup in hardware, ie: TE410P running on dual-xeon system,
however I'm running IVR only.  I start getting the I-frame errors above
about 80 simultaneous calls.  I do not get IRQ misses at all.  Also I do not
get the startup error messages.  The errors I get the most under load are
the frame retransmission messages in /var/log/asterisk/messages.  Do you get
those as well?

Since you are getting IRQ misses, you may have some basic problem, ie:
something keeping the zaptel driver from getting around to servicing the
TE410 interrupts.  I think that they have to be serviced without fail every
1 msec, or errors start occurring.

Which kernel are you running?
What does your Perl script do?
Did you try disabling mysql logging to lower the disk load?  Maybe the disk
driver is interfering with the zaptel driver interrupts. 

Regards
Scott
