Rsync problem - oops occurred (0.42)

All,

I've been doing a nightly rsync of a 36GB SCSI drive on my 1 CPU SS20 to
another on the same system, and it was working flawlessly up until 10 
days ago.  Last
night and one time prior it caused some problems and a kernel oops.  Was 
wondering if the obvious fix here is upgrading to 1.0.  It would be a 
bit of a chore at this point.  This last time it crippled the system.

Any help appreciated,

-charles


kernel: 2.4.19-1.2sparc 0.42 OS
