Description:With CVS head (asterisk & zaptel), I can realiabily reproduce this problem...

show channels will crash asterisk, and sometime it may restart if started by safe_asterisk, but sometimes it doesn't

and if it gets restarted by safe_asterisk, there is one occasion where it bridge an incoming call with an outgoing call made from a SIP phone. The incoming caller can hear the  DTMF dialed from the SIP phone.

The machine I had this problem is running 2 X100P cards.
Comments:By: heison (heison) 2004-10-21 14:41:53

when there is no active channel, show channels works just fine...
Verbosity is atleast 11
Core debug was 0 and is now 7
pbx*CLI> show channels
       Channel  (Context    Extension    Pri )   State Appl.         Data
0 active channel(s)

but when there is a channel opened (Zap in this case), show channels will crash asterisk:

   -- Executing BackGround("Zap/1-1", "ext-or-zero") in new stack

that's strange, cause all this is in the function quit_handler. And i dont see why that could happen. When doing a show channels it's in the function handle_chanlist. I'd like to know why that could happens too.

Have ya tried with the latest CVS version to see if the bug is still there?
By: Brian West (bkw918) 2004-10-21 23:54:48

well I can't get show channels to do this now...

but I do get this wonderful tidbit:

channel.c line 625 (ast_channel_free): Error destroying mutex: Device or resource busy
By: heison (heison) 2004-10-22 10:46:09

with a fresh CVS checkout, the problem seem to have gone away.

YOu should always do "make clean ; make install" or possibly do a fresh checkout before placing a bug.

Because a lot of structures are changing in CVS, it's important to be sure builds are *clean*.
