I've seen it a few times when running in a VM that didn't have enough memory available. The clue for me was looking in dmesg and seeing messages from the OOM-killer saying it was terminating spamd. I don't know why it would often work on subsequent runs, but allocating more memory to the VM seemed to make the problem go away. Cheers, Adam.
