NFS problem in server

Hi,

In our production system one of the users complained of receiving the error below in the /var/adm/messages :

Apr  9 00:05:03 L28emmol1 EV_AGENT[2359]: [ID 881973 daemon.error] Agent Main --Estream construct failed. Err: EMULSocket::recv()
Apr  9 00:05:03 L28emmol1 nfs4cbd[1999]: [ID 491311 daemon.error] nfssys NFS4_SVC failed
Apr  9 00:05:03 L28emmol1 nfs4cbd[1999]: [ID 254324 daemon.error] unable to register new connection: client 10.67.24.62.131.108 has dropped connection
Apr  9 00:05:03 L28emmol1 ftpd[11347]: [ID 572618 daemon.error] getpeername: Transport endpoint is not connected
Apr  9 00:05:08 L28emmol1 EV_AGENT[2359]: [ID 558310 daemon.error] Agent main -- unknown exception
bash-3.2$

My question is why does the ip display like above :

10.67.24.62.131.108

Why does it have .131. & .108 at the end? If it is a port, then only one number should be valid. But now it is showing 2 numbers after the 10.67.24.62 and those numbers don't even seem like a valid port number. And can I really confirm that 10.67.24.62 is actually an IP address?

These are some of the steps I have performed to address this problem :

# ping 10.67.24.62
10.67.24.62 is alive
# rpcinfo -u localhost nfs
rpcinfo: RPC: Program not registered
program 100003 is not available
# /usr/bin/rpcinfo -u localhost mountd
rpcinfo: RPC: Program not registered
program 100005 is not available
# ps -ef | grep mountd

    root 28373 28372   0 19:38:00 ?           0:00 /usr/lib/autofs/automountd
    root 28372     1   0 19:38:00 ?           0:00 /usr/lib/autofs/automountd
# /usr/bin/rpcinfo -u localhost rpcbind
program 100000 version 2 ready and waiting
program 100000 version 3 ready and waiting
program 100000 version 4 ready and waiting
# /etc/init.d/nfs.server start
# rpcinfo -u localhost nfs
rpcinfo: RPC: Program not registered
program 100003 is not available

>>>>Even after starting nfs, it shows RPC error.

How do I resolve this problem?

I suspect 10.67.24.62.131.108 is printed by code designed to only display bytes so that might simply be:
IP = 10.67.24.62
PORT = 131.108 (131*256)+108 33644
