High load when nfs server falls

[Viktu Pons i Colomer]

Hi. I have a problem with my servers. We have 4 disc servers, serving
nfs for an amount of 20 servers.

The problem is that when a disc server crashes, or I've to shut it down
for maintenance, the load
average of all my linux boxes grows up to 50! , so they become unusable.
My solaris and Hp-UX
boxes won't do that. Is there any way to make linux not growing the load
average?

TIA!

FreeBSD is another free Unix variant that has fairly decent
networking capability. Linux appears to have an NFS client that
would embarass Microsoft's worst engineer.

Until the Linux folks start paying attention to decent programming
practices, just unmount the servers before maintenance.
