Exception occurred while retrieves the full state from the target member

[lahiru amalka yapa]

Hello,

we are facing org.jgroups.StateTransferException while retrieves the state from the coordinator. Following code is used to get the sate,

try {
                jchannel.getState(null, 5000);
     } catch (Exception e) {}

In order to get and set state, we have overridden the following methods,

@Override

public void getState(OutputStream output) throws Exception {}

@Override

public void setState(InputStream input) throws Exception {}

when node try to get the status using coordinator, it fails due to following error,

org.jgroups.StateTransferException: state transfer failed
