Summary:                    /include/asterisk/lock.h:531
__ast_pthread_mutex_unlock: app_mixmonitor.c line 277 (mixmonitor_thread): Error
releasing mutex: O
Description: 
When recording any incoming call with mixmonitor these messages slam the
CLI
The call is recorded properly for playback but this looks like bad
locking...
