I am using an MVME147A-1 (25MHz, 8MB version) board running vxWorks,
and am experiencing a bizarre problem: Given enough time, the board will
freeze up, requiring a reboot. The amount of time varies from seconds
(sometimes it dies while loading the symbol table) to hours, but eventually
(e.g. overnight) it will always hang up. The problem seems to be related
to the ethernet interface, since it doesn't happen if I disconnect the 
ethernet cable after boot-up. Wind River has confirmed the existence
of the problem, but nobody seems to know what to do about it. I would
appreciate hearing from anyone out there who has the same problem -- better
yet, someone who has a fix for it! 
If I find a solution, I'll post it here for everyone's benefit.
