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 2907/4908/7815 mbufs in use (current/cache/total) 2255/4551/6806/25600 mbuf clusters in use (current/cache/total/max) 1312/2272 mbuf+clusters out of packet secondary zone in use (current/cache) 0/119/119/12800 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/6400 9k jumbo clusters in use (current/cache/total/max) 0/0/0/3200 16k jumbo clusters in use (current/cache/total/max) 5236K/10805K/16041K bytes allocated to network (current/cache/total) 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0/0/0 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile 0 calls to protocol drain routines ============ -- Regards, Sherin On Sat, Jan 23, 2010 at 7:12 PM, Thiago Damas <tdamas@> wrote: > Hi > Nfsd as udp or tcp?
