I have been wrestling with this for a while. I suspect the most useful
info is the stuff that flashes by on the monitor attached to the
RaQXTR/550 - a RaQXTR with 2GB RAM and 4 30GB disks configured to use
RAID0 and the RaQ550 OS with all patches. The stuff flying by on the
monitor seems to be messages about paging failures and panics. I
suspect a memory problem but can't really test easily because the
memtest package available from Sun reads the ROM which says it has
512MB -- I have no idea how to change this. I am about to start
pulling chips until it stops failing.
