That bug seems to be characterized by crashing under load while I'm seeing it lock up completely with no evidence that I can find that points me to why. I'm open to advice for troubleshooting. I'm nearly to the point of having a raspberry pi connected to the reset button. But that just treats the symptom without finding a cure and is potentially really bad for my filesystems.
