DFM error: Java.net.SocketException: No buffer space avaliable ( maximum connection reached)

NetApp Oncommand/DFM/NMC error: Java.net.SocketException: No buffer space avaliable ( maximum connection reached)

*Update-- The below solution worked for me temporarily. The permanent fix as to install the windows hotfix

Kernel sockets leak on a multiprocessor computer that is running Windows Server 2008 R2 or Windows 7

This is for my future reference:
This is the error i came across OnCommand running on windows 2008 R2 server.

The solution is to increase the connection in windows 2008 server.

1) Open the windows command line and check how many ports are opened.

C:\>netsh int ipv4 show dynamicport tcp

Protocol tcp Dynamic Port Range

---------------------------------

Start Port      : 49152

Number of Ports : 16384

2) Increase the number of ports with the command

C:\>netsh int ipv4 set dynamicportrange protocol=tcp startport=5000 numberofports=60536

3) confirm again

C:\>netsh int ipv4 show dynamicport tcp

Protocol tcp Dynamic Port Range

---------------------------------

Start Port      : 5000

Number of Ports : 60536

Thanks for reading.
