It may well be -- there have been quite significant architectural improvements to socket life cycle (etc) between 6.2 and 7.x releases, which may well close the race causing this panic. However, we'll probably need to learn a bit more in order to decide for sure. Could you convert the trapping instruction pointer to file+offset in the source code?
