Clebert- I tried running your new large message example but increasing message size to a real "large message size". (1MB is not large) On 100MB it crashed: | [java] org.jboss.jms.example.SpawnedJMSServer out:STARTED:: | [java] Sending message of 104857600 bytes | [java] Large Message sent | [java] 09:13:18,868 WARN @Thread-0 (group:jbm-pinger-threads-7226213) [RemotingConnectionImpl] Connection failure has been detected Did not receive pong from server, active true client true:2 | [java] 09:13:19,032 WARN @Thread-0 (group:jbm-pinger-threads-7226213) [RemotingConnectionImpl] Connection failure has been detected Did not receive pong from server, active true client true:2 | [java] org.jboss.jms.example.SpawnedJMSServer out:09:13:19,078 WARN @Thread-5 [RemotingConnectionImpl] Connection failure has been detected Netty exception:0 | [java] org.jboss.jms.example.SpawnedJMSServer out:09:13:19,078 WARN @Thread-5 [ServerSessionImpl] Client connection failed, clearing up resources for session 629fe759-20f0-11de-b197-b5595771a611 | [java] org.jboss.jms.example.SpawnedJMSServer out:09:13:19,216 WARN @Thread-5 [ServerSessionImpl] Cleared up resources for session 629fe759-20f0-11de-b197-b5595771a611 | [java] org.jboss.jms.example.SpawnedJMSServer out:09:13:35,508 INFO @Thread-1 [JBMBootstrapServer] Shutting down | t | We need to be able to send messages 4GB 10GB no problem.
