What in your opinion is a lot of retransmissions? Today I am seeing
around 0.7%.
Client rpc stats:
calls retrans authrefrsh
23695 166 0

I am using the standard kernel provided by redhat for this machine.

Neither the open-source nor closed source drivers appear to be loaded,
are these drivers only loaded when going to runlevel 5 (or starting x
manually?)?

I have also started to mount the NFS volumes using TCP, I am no longer
getting the NFS server not responding error messages.

However, if this is just hiding a problem i would like to find out for
future reference.
