Hi TC, I followed your instructions. Today I managed to lock up one of our Asterisk boxes with an incoming SIP call.
It locks up right after seeing I this line: Dec 8 13:48:34 WARNING[4101]: File chan_sip.c, Line 456 (retrans_pkt): Maximum retries exceeded on call [EMAIL PROTECTED] for seqno 1058 (Response) I was able to follow down to STEP #7 of your Deadlock debug Instructions, but the file in step #8 is not present. In any case here is the relevant thread that is locked: Thread 6 (Thread 4101 (LWP 8372)): #0 0x420292e5 in sigsuspend () from /lib/i686/libc.so.6 #1 0x40039679 in __pthread_wait_for_restart_signal () from /lib/i686/libpthread.so.0 #2 0x4003b4b9 in __pthread_alt_lock () from /lib/i686/libpthread.so.0 #3 0x4003816e in pthread_mutex_lock () from /lib/i686/libpthread.so.0 #4 0x41be8235 in retrans_pkt (data=0x8138e50) at ../include/asterisk/lock.h:89 #5 0x08051e05 in ast_sched_runq (con=0x80eeac8) at sched.c:355 #6 0x41bfba86 in do_monitor (data=0x0) at chan_sip.c:5409 #7 0x40036fef in pthread_start_thread () from /lib/i686/libpthread.so.0 (gdb) thread 6 [Switching to thread 6 (Thread 4101 (LWP 8372))]#0 0x420292e5 in sigsuspend () from /lib/i686/libc.so.6 (gdb) frame 2 #2 0x4003b4b9 in __pthread_alt_lock () from /lib/i686/libpthread.so.0 (gdb) Is this enough to open a ticket in the BUG tracker? Is there anything else I should look for? I have not restared Asterisk yet.
