Description:Hi

We are using asterisk-1.4.21 , libpri-1.4.4 and zaptel-1.4.11 and during the calling on daily basis asterisk goes unresponsive and both outbound and inbound calls stops .

At this point of time we have to stop asterisk and start it again .

We are using Single E1 card with asterisk and dialing on zap channels and transferring the calls on SIP channels .



****** ADDITIONAL INFORMATION ******

We have tried taking the output of show channels which was

show channels
Channel              Location             State   Application(Data)
Zap/pseudo-139279208 s@default:1          Rsrvd   (None)
SIP/104-09a51510     50104@local:1        Up      MeetMe(50104)

-------------------

Then we tried taking the output of core show locks but that was also unresponsive

hyd-static-171-8-12-61*CLI> core show locks
hyd-static-171-8-12-61*CLI>exit


Then we have taken the backtrace of the asterisk at that time and m attaching it .

bt
bt full
thread apply all bt
thread apply all bt full
list

Looking for the positive response like always .

It was not going beyond that .

Tried taking asterisk -rx 'core show locks' but this command was also not going ahead .

Have taken the backtrace of the asterisk at that time .

Please guide what needs to be done .

Thanks

Please update to the latest 1.4 SVN.  We discovered an issue yesterday which can cause 'core show locks' not to display anything.

Fix a typo in the non-DEBUG_THREADS version of the recently added DEADLOCK_AVOIDANCE()
macro.  This caused the lock to not actually be released, and as a result, not
avoid deadlocks at all.  This resolves the issues reported in the last while about
Asterisk locking up all over the place (and most commonly, in chan_iax2).
