Here is my dmesg output, and btw, sorry.. the perl script was not running
on the NFS volume, just regularly on a regular 4.0 box, and it crashed the
box (yes, I had login limits set), I was just giving another example of
what seems to be some instability in 4.0 under high loads..
Here my dmesg from the raid/nfs server:
