Russell Bryant 5e80b9d09a Fix some issues with rwlock corruption that caused deadlock like symptoms. ... When dvossel and I were doing some load testing last week, we noticed that we could make Asterisk trunk lock up instantly when we started generating a bunch of calls. The backtraces of locked threads were bizarre, and many were stuck on an _unlock_ of an rwlock. The changes are: 1) Fix a number of places where a backtrace would be loaded into an invalid index of the backtrace array. It's an off by one error, which ends up writing over the rwlock itself. 2) Ensure that in the array of held locks, we NULL out an index once it is not being used so that it's not confusing when analyzing its contents. 3) Remove a bunch of logging referring to an rwlock operating being done with "deep reentrancy". It is normal for _many_ threads to hold a read lock on an rwlock. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@184531 65c4cc65-6c06-0410-ace0-fbb531ad65f3		17 years ago
