Howard, I'm facing the same problem. I am running 4.0-current / 4.0-stable on a Dual-PIII-733, 1GB RAM, 2 Adaptec, 300GB disk. I have had sudden crashes/reboots as bad as not even producing core dumps or dropping into kernel debugger. I had several guesses, one of which was the 64K block size on some of the disks I use. This proved to be wrong as I had a crash 2 days ago (again in UFS) from a chgrp -R across a large number of files (around 2GB of small stuff). Another guess that it is SMP related proved to be wrong when I compiled a uniprocessor kernel and the problem did not go away, it just occured an order of magnitude less frequently. The error pattern has changed since, I do get core dumps again. What is common to all of them is that they occur in UFS. My guess is that there is some sort of locking problem or locking race, but thats very vague. As for you, my knowlegde about the intrinsics of the file system is very limited. I repeat my offer to make the crashes I've got available to -hackers so they can have a more detailed look. Joerg -- Joerg B.
