Summary:                    We could NOT get the channel lock for SIP
Description: 
We see this log before the asterisk hang. This asterisk was working very
fine, now I install a transcoder card and the asterisk randomly hangs (2 or
3 times for day) with these errors. I tried with other machine, and other
version 1.4.17 with the same result. I must to reboot the server because a
kill -9 command doesn´t work. If I remove de card there is no crash any
more. I don´t know if is a zaptel or asterisk problem, Plese show me how
create a debug if you need it.

The zaptel driver know the transcoder card:

CLI> transcoder show
0/0 encoders/decoders of 92 channels are in use.

regards

Diego

I wrote similar bugreport due to same errors
http://bugs.digium.com/view.php?id=13115, except that I don't
have crashes and not using transcoder.
You will be probably asked to compile asterisk with 
MENUSELECT_CFLAGS=DONT_OPTIMIZE DEBUG_THREADS LOADABLE_MODULES
DEBUG_CHANNEL_LOCKS
and analyze coredump with 
gdb asterisk coredumpfile
