If you have downtime and don't mind running Asterisk under valgrind, that
would be great.
I think sending both sides of the call to the musiconhold app would do the
trick. It seems like it's a matter of chance whether the problem will or
won't occur, though. The problem actually occurs when musiconhold is
finished, though. So a bunch of really short calls that have musiconhold
started and then get hung up after a second or two would cause the issue to
be more likely to happen.
Oh, and just as a reminder (even though valgrind.txt says this), running
under valgrind may actually cause Asterisk not to crash, but it may log
useful output anyway. So if you run some tests with valgrind and don't get
any crashes to happen, just remember that its output may still contain
useful information.
