I did see that sort of thing, particularly if you're also seeing the load stay up, where basically one of the threads goes into an infinite loop. I sent Russ a core dump and a few other tidbits, but I think he was pretty busy with some other things at the time. Not long after that I moved to using FreeBSD rather than Linux, and I've had a lot fewer issues there. The behavior feels like a thread getting stuck in a spin lock with no one else releasing the lock, but I haven't dug deep enough to see if such a thing is at all possible. It does seem to show up most when running fossil though which would seem to be some kind of clue. BLS
