After a connection is established with javakdb; when there is no messages sent for sometime, I see that the connection is dropped as there is a error when trying to send some message again. Is there any default timeout? Can this be changed?

Neither kdb+ or it's Java interface implement any default closing of sockets.

You can set up connection open/closing logging handlers in kdb+ to help debug:
