Summary:                    crash when calling ao2_unlock inside
pthread_timer_disable_continuous
Description: 
When under heavy load we have experienced random crashes (6 times in a day)
at the same point in the code. The load is with about 200 channels, 70
users and making a lot of calls. It was very stable until we started
reaching a certain level of usage.
