[asterisk-users] Core dumps when Releasing clone lock

[Øyvind Albrigtsen]

Hi,

Our Asterisk server has started core dumping more often, which seems to 
be related to when it releases the clone lock, and it stops masquerading 
the channel.
So, I wondered if anyone had an idea what causes these masquerading 
attempts.

Our system is running: Asterisk SVN-branch-1.2-r31555M.
