Description:We experiment several majors problems on our asterisk platform

1st error:
NOTICE[7145] chan_zap.c: PRI got event: HDLC Abort (6) on Primary D-channel of span 3

2nd error :
Ring requested on channel 0/21 already in use on span 1.  Hanging up owner.

3rd error :
chan_iax2.c: Avoiding IAX destroy deadlock

For these 3 errors, there is no core dump. Asterisk console is still working, with these errors in loop, but we cannot receive any more calls (busy tone for the callers).
Unfortunately, the reproducibility of this problem is random... But we experiment one of these issues once or twice a week.
For the fist two issues, could it be a problem with our carrier ? a problem with T1?

do you need additional information ?

Thanks for help.

You are experiencing a deadlock scenario, that starts at the pri level. There has been some requests for information posted in 8957: can you please review the postings there and see what you can help with?

Do I need to apply chan_zap.c patch for you to have debugging flags ?

If you can confirm that this is the fix to your problem, it will be.  Is that the case?
