I've bugged Sun about it, all they did was point to Bert though ;-) I only see this happening when using the fork option, and then again only when getting a lot of queries. It happens every couple of weeks, sometimes it runs for a couple of months even. Restarting often doesn't change a thing, it looks very much like a race-condition so the less queries the less chance you'll see it (in my experience).
