We're getting desperate. Are other people that use SMP with a similar
setup (4-way Xeon, 2 GB RAM, lots of disk [AMI Megaraid raid5])
seeing similar instability, or should I look for a hardware problem?
We're using 36-chip RAMs on this machine, but with this level of
hardware (AMI Megaplex, fits up to 8 GB of RAM) that should not
be a problem - right ?
Thanks for _any_ insights
