CELL-02559:There is a communication error between MS and CELLSRV

To See the Exadata Storage cell status we can run the following command :

CellCLI> list cell detail

At the bottom of output there are following three lines to indicate the exadata storage software components and status 

         cellsrvStatus:          running
         msStatus:               running
         rsStatus:               running

Which represent that exadata storage is running fine.

This morning I was getting CELL-02559:There is a communication error between MS and CELLSRV.

I have restarted the services and then it becomes in good state again.
CellCLI> alter cell restart services all
