Summary:                    chan_zap causing reset on E1 and eventually crashed
asterisk
Description: 
I have a TE410 and TC400B installed under Fedora 7 kernel 2.6.23.1-10. with
asterisk-1.4.13, zaptel-1.4.6, libpri-1.4.2.  I have two E1 installed on
the TE410 card my calls are all going from IP to PSTN.  When I have above
40-45 calls (if it is less than 40 I havent noticed any problems) after a
while I start getting error similar to:  
[Nov  6 17:32:18] ERROR[32610] chan_zap.c: !! Got reject for frame 30,
retransmitting frame 30 now, updating n_r!
the number of errors increase and all of a sudden one of the E1s resets
and all the calls drop on that E1. The problem repeats and at some point
the other E1 resets which E1 resets is pretty random.  Then after several
of these errors the asterisk core dumps.  I have tested the hardware with
the help of digium support and have eliminated the hardware as an issue.  I
also tested the E1s and they are clean.  I also to the best of my ability
eliminated the problem being caused by conflict of any unrelated modules. 
I have the full debug (crash at 18:29:37) also the core dump both are
tar.gz(ipped).. I am available to provide further testing with live calls
if we need to get more data or test with live calls if there is a patch.
Thanks
