ok of those commands some interesting info was from dmesg...
on one machine i had
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
file: table is full
from dmesg
on the other machine
looutput: mbuf allocation failed
nfs server 172.16.0.101:/bravenet1/home: not responding
looutput: mbuf allocation failed
looutput: mbuf allocation failed
looutput: mbuf allocation failed
nfs server 172.16.0.101:/bravenet1/home: is alive again
looutput: mbuf allocation failed
looutput: mbuf allocation failed
i doubt that mbuf allocation failed was from the nfs server timeout that
one time....but cannot be certain......this help you at all?
