Thanks to all who responded. I have not yet resolved the problem
but the consensus seems to be some sort of hardware problem.
Will post a further summary when available.
> System : 1200 5/533; 640 MB; 4.0D no patchkits installed
> Problem: System crashes during defrag of /usr (usr_domain#usr).
> While investigating I was able to get the system to crash while
> performing the following:
> # ls -R /usr
> # verify usr_domain ! done from single user mode
>
> There are no advfs errors in either the messages file or the crash-
> data file. The only error that occurs is:
> Mar 29 10:41:36 LIME vmunix: panic (cpu 0): System
> Uncorrectable Machine Check
>
> Another note : this file system does not get backed up (this is my
