All,

We are running OnTap v8.1.3  7-Mode as vfiler, all of sudden some of the NFS shares started giving mount an error on all exported servers with rpc timeout error on TCP port..but when we switched to UDP port it works fine..Does anyone have this isssue ? Please let me know what caused this and how to resolve this issue..

I have tried changing settings of the router in the Netgear router login page but I cannot find the proper option to changes the UDP timeout error and surely you can also change the TCP with a simple tool.
