Bug in the Python engine
We have discovered a bug in the Python engine. It has to do with a debug feature that we turned on in beta to hunt reference leaks. Basically we added
which adds the sys.getobjects function. There was an unfortunate side effect that the counter used was only 32 bit. Which turned out to be a problem when ~6000 users had been playing for some time. We never understood why we had node deaths, after the peak hour. This was the reason, a build up in the alloc counters. A patch will be issued to the servers tomorrow, so expect a lot less node off-lining as of tomorrows downtime.
