Do you see the same problem if you write something small and hard-coded in c that uses libesl?  That message about lost events typically only happens when the receiver can not process messages fast enough off the socket, and the queue fills up.  This could be the fault of the java sockets, java esl library, or your code in java blocking while processing a message.
