we have a client and a server. The client at some point of time, during one of the several communications with server gets exceptions:

org.omg.CORBA.COMM_FAILURE: IOException: java.net.SocketException: Socket closed  vmcid: 0x0  minor code: 0  completed: No
        at org.jacorb.orb.etf.ConnectionBase.to_COMM_FAILURE(ConnectionBase.java:143)

and

[jacorb.giop.conn] ERROR : Failed to write GIOP message due to COMM_FAILURE

[jacorb.giop.conn] ERROR : GIOP connection closed due to errors during sendMessage

and this exception comes at java console of the client and is not caught in the client code even though client catches a generic exception on all server invocations. I get a brand new reference of the server from the naming service.
The new instance of the server is on the IP and port, even then no further commmunication between the client and server is possible and the request processor thread executing the client code dies at the server invocation. I think that once a "Broken Pipe" happens, the socket is dead, and any further reuse by the orb is doomed to failure.  As it is,
once this error happens, only killing and restarting the client resolves
the problem. 

Please help me regarding the issue.
