 * If you have ``logic parity'' instead of true parity you have defeated
 * 75 % of the purpose of even having parity on memory.  

75%?  I thought that was 100% ;)  (Ok, maybe it can check the memory
bus failure, but how often would that happen?)

 * 							 I would highly
 * encorage you to try a swapout with some ``real parity'' memory and
 * more than likely watch your problem go away...

I'd never buy a "logic parity" board myself, but unfortunately, these
machines are donated to our project (they aren't even supposed to be
running FreeBSD!) so I can't change anything in them. :(

So, do you think this is a memory problem?  Is there some other test I
can run, other than stressing the SCSI system?  (It doesn't crash when
I run the "fast bcopy" benchmark, and I think that thing stresses the
memory system a lot....)
