The disgusting thing about threading bugs is that there's no such thing as as "never worked". We do test one periodic BC example, and it gets run with 2 threads at least 10 times a day, and I've never seen it fail. Hmm... that's probably partly a Heisenbug caused by race conditions being less likely in slow debug-mode compilations. Maybe I need to add an opt-mode run to our tests; my own opt-mode tests are always with one thread. > We've just never got around to fixing it. Glad you tracked it down. Well, let's hope that that it is it. I'll ping you when there's a fix in so you can test and see if there are any deadlocks still triggered by your stuff. --- Roy ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
