asterisk users - Nov 2003 - Crash - What is happening here???

The following transfer led to a crash of asterisk, without leaving a core
or any utterances in messages or debug file. It looks like the zombie which
was created during the MASQ-transfer was not cleaned up... But why did 
it start
a Dial??? And... why does Asterisk die when this happens??

Thanks!!!

Michiel

Small tutorial:

these errors are too generic to be solved in such way...
"hey my asterisk crashed, why it did?"... there're many
reasons...

First: set "ulimit -c unlimited" on the console
from which * starts, to let it dump cores.
Then start it with 'g' in his parms , like
"asterisk -vvvgc", to enable debugging...
then when it crashed, run gdb on the core and
backtrace it....

also: try to find a way to reproduce the crash.
random crashed aren't very useful...

and... report also asterisk version, kernel, distro,
blah blah blah

Michiel, that message isn't only for you, but
your post triggered my thoughts to "how to report a crash",
for anyone that just jump on th ML and say
"my asterisk crashed. please say me why"...

bye, matteo
