The problem went away when I turned off hyperthreading. With WITNESS turned on, the TIMEOUT messages were accompanied with some locking message or other, but I haven't had a chance to reproduce the problem and record the exact message. Given this, and the fact that it goes away when running UP, I speculate that it may be a locking problem somewhere. -Peter-
