thanks for the proposals... however I fail at 1) !
I tried doing again the same thing: sharing over NFS with other boxen 
building and compiling heavy stuff on the same system - it stayed up for 
several days.

Then I thought of stress-testing. I launched bonnie++ several times on 
on edisk, on the other and then launched two instances in parallel on 
both disks, repeatedly.
No problems!

I really wonder what happened the first time... what error it was? For 
sure the system acceptable stable. Also, this way, I cannot say 9.3 was 
unaffected.. albeit in A year or so I never had to reboot forcibly the 
system it was very stable.

I suppose that the disks aren't in a too bad shape and all seems stable 
even with torturing, bonnie writes gigabytes and thousands of files.

The only thing that bonnie doesn't dest is concurrency with other 
devices - eg. high network activity with concurrent high disk activity.

I could try running bonnie++ over NFS??
