[asterisk-users] Asterisk Core dump

[Anthony Musaluke]

Hi,

I have a strange problem that started  some few days back. Every so often my 
asterisk (version  Asterisk 1.2.11) comes up with an error and either does a 
segmentation fault or dumps core, but then it restarts automatically. Here is 
the error when that happens:

And running gdb asterisk on the core produces the result below:
