Java APIs

i implemented chat by establishing the connection using sockets.. the application works fine when running on a single machine but exits after somewhile when two remote machines are connected.
the time after which the error occurs is random not dependent on number of messages exchanged or the time for which connection was setup.

the error code is as follows:-
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
