Thanks for the response, Steve! Our broker is not public and the clients are all internal applications and not internet users.
we intermittently altho frequently see this error when the client is trying to publish a message. Our clients are both publishers and subscribers. For every publish, the client creates a new connection, sends the message and closes the connection. it receives the message on a separate connection. Our clients also do DB intensive operations in parallel (not on the ActiveMQ thread) but in separate threads. If for some reason , the client is pegged doing the DB operations could this cause the client to not respond in a timely manner to the broker and as a result we see these timeout issues? thanks again! jaya stevec wrote: > > I do not know why they classify as an "ERROR".
