Major When JNLP slave detect ping timeout, it tries to reconnect. But if master have not noticed the timeout yet, it rejects the new connection from slave. JNLP slave agent process aborts once the connection is rejected in such a way.
STDOUT of JNLP process:

If rejecting the connection is the correct behavior of the master then the agent should keep retrying so the system as a whole can recover.
If the rejection is unwarranted because the old connection was dead and the master is to slow to realize this, then the issue lies with the code running on the master node.
