Error filling /var/adm/messages

I have Solaris-11 non-global zone running under Solaris-11 global zone. Every few minutes, this message is getting in /var/adm/message of non-global zone

Aug 31 08:31:53 zonnjc002dbp01 statd[4428]: [ID 766906 daemon.warning] statd: cannot talk to statd at NAS1, RPC: Timed out(5)

NAS1 is already mounted as NFS and working good.
I have already tried below steps to

svcadm -v disable nfs/status
rm /var/statmon/sm.bak/NAS1
svcadm -v enable nfs/status

Still I am getting this message continuously.

What you did was correct, but only to be done after you were CERTAIN that the local solaris box can talk to the remote box. Assume it cannot talk. That is what RPC failure means.

I would guess there is another non-NFS problem going on. Probably on the remote box. Check services and dmesg over there.

That is coming from SAN. I will check with SAN people on this. Thanks Jim
