Summary:                    kernel oopses with similar stack traces
Description: 
My asterisk-box running asterisk-1.4.22 and fedora kernel
2.6.26.5-28.fc8PAE and 2.6.26.6-49.fc8PAE constantly crashes after
several days, leaving the same stack-trace every time. (Attached.)
Zaptel versions 1.4.11 and 1.4.12 also show the same problem.

The crashes appear after a few days, I couldn't trigger them with
phone calls.

kernel-PAE-2.6.24.4-64.fc8 together with a zaptel SVN version from
2008-08-05 worked fine. (An earlier version had stack overflow
problems with this kernel.)

Unfortunately the stack traces seem to be subsequent errors following
a memory corruption so I suppose the stack traces won't be very
informative.

---------------------------------------------------------------------- 
The snprintf patch seems to fix the problem. Using 2.1.0-rc5, the box runs
without a crash for 20 days now.

The only messages, I get are:
---------------------------
Unassigning channel 0/1!
Unassigning channel 0/1!
Unassigning channel 0/19!
Unassigning channel 0/19!

I'm using "echo 1 > /sys/module/dahdi/parameters/debug" and "echo 1 >
/sys/module/wct4xxp/parameters/debug".

Thanks,
