Been having issues occasionally with all videos in a room freezing after 60  
minutes or so. Looking at one of the erizo logs today, I see it terminated  
with a “boost: mutex lock failed” error. Other similar freezes just showed  
no error messages, but clearly the erizo log stopped suddenly.

Including the last few lines from today’s freeze below:
