[asterisk-users] unable to get channel lock BAD BAD BAD

[Tim Uckun]

I am seeing the following in my log file (standard trixbox install).
One seems to be complaining about an error in the dialplan but it
won't tell me what file or what line. The other (maybe related) is
complaining about a channel lock.

How to do go about trying to figure out what the problem is and how to solve it?
