pretty sure the root cause is with chan_sccp.so, but not sure how to
prove it.
I recently upgraded from CVS-head to 1.2.1 and the chan_sccp from
12-17-2005. Now, once or twice a week, I get this on the console:
Jan 31 10:39:08 WARNING[10586]: channel.c:784 channel_find_locked:
Avoided deadlock for '0xbf1013e0', 10 retries!
Once this happens, all of my sccp phones drop offline and attempt to
register. I get no sccp messages on the console. There's really
nothing on the console to indicate any sort of problem. If I try to
do an "unload chan_sccp.so" and then load it back, all of my SIP
phones lose their registrations, none of my Zap channels work and I
have to kill Asterisk and restart it.
Is this an Asterisk problem or an SCCP problem? Help!!
It did it to me again. I enabled full logging and here's what I get.
All the 7910's drop off line and try to reregister. All SCCP messages
on the CLI stop. Anytime I try a "show channels" I get the Avoided
deadlock message. Here's what the logfile shows. Any ideas? And is
there a way to fix the deadlock without restarting Asterisk?
