> Monitor still alive after channel is hanged up.
> Dialplan example:
> {noformat}
> exten => _4XXX,n,Monitor(gsm,${UNIQUEID},b) 
> exten => _4XXX,n,Dial(SIP/KMPX/1${EXTEN:1})
> exten => _4XXX,n,Hangup
> {noformat}
> After hanging up ast_monitor_stop() called one time with one of channels. If monitor started on other channel then ast_monitor_stop() do not call with other channel. After each call asterisk holds output files. And after some time asterisk cannot create any descriptors and I need restart asterisk.

> This affected in 11.11 but I see similar code in trunk. I do not check trunk but I guess that situation is present in trunk too.
> I suggest patch in attached file. Patch to revision 425385
