Strange network issue in freebsd 8

[Sherin George]

Hello Thiago,

I have configured NFS clients to use TCP.

Here is the present output of "netstat -m". Right now, server is working
fine.

============
myserver# netstat -m

2255/4551/6806/25600 mbuf clusters in use (current/cache/total/max)

0/0/0/3200 16k jumbo clusters in use (current/cache/total/max)
