When trying to start MServer with the default port (1586), since we are using socket to connect between the MServer and all clients, the socket file name is like mserver-1586= and if that file has already been created by some other user, the MServer start will fail with the following exception:

Exception in thread "main" java.net.BindException: Bind failed
       at sun.isolate.util.UnixMServer.initializeListenFD(Native Method)
       at sun.isolate.util.UnixMServer.initListener(UnixMServer.java:29)
       at sun.isolate.util.MServer.mainLoop(MServer.java:194)
       at sun.isolate.util.UnixMServer.main(UnixMServer.java:15)

This should be enhanced to prompt the user with correct error message and possible action they should take to solve the problem.
