Question: I get this error what does it mean?
org.jboss.mq.SpyJMSException: Connection Failed; - nested throwable: (java.io.IOException: ping timeout.) Answer: Each connection pings the server once every PingPeriod. This is configured on the ConnectionFactory (e.g. jms/deploy/uil2-service.xml) and defaults to 60 seconds. Its purpose is for the client to be able detect that the connection with the server has been broken. The mechanism is as follows: 1) Client sends a ping to the server and rests for the PingPeriod 2) After the PingPeriod has expired it checks that it got a Pong from the server 3) Repeat from 1 Reasons for Ping failure: 1) The connection is broken 2) Something horrible is going on, e.g. very long garbage collections or massive amounts of paging means the ping/pong doesn't get enough cpu to process in time i.e. either the client or server is not failing big time to keep up with requests 3) You send a large message that takes more than PingPeriod to send over the connection, the ping or pong waits behind the message for its turn to be processed UIL2 has a ChunkSize that similuates a Pong when that many bytes are sent over the network to avoid this problem. 4) Some other problem like a deadlock (see "Read This First" in this forum) for how to debug this.
