> We have been experiencing Asterisk deadlocks for the past week, from at the time, what seemed like nowhere. We upgraded to the latest 10.7.0 stable and enabled the debug flag and disabled optimizations in hopes to catch the deadlock. It seems from looking at the locks we have some sort of problem with our TCP connected SIP devices. Things are now starting to make sense as connecting TCP SIP devices is something newer that we started to do. The deadlocks we experience happen anywhere from every-other-day to several times a day, all involving a restart. Would you be so kind as to look at the attached backtrace and locks output?
