We use a netapp and I had to muck around with the default settings under
rh7.2 to get reliable behaviour. Note that our database does not sit on a
netapp, only our semi-static web content does.

Here's the settings I added, at the behest of one of our unix / linux
ubergeeks:

timeo=10,retry=1,bg,soft,intr,rsize=8192,wsize=8192
