[jboss-jira] [JBoss JIRA] Created: (JBMESSAGING-1701) Server closes connections from alive clients

Server closes connections from alive clients -------------------------------------------- Key: JBMESSAGING-1701 URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1701 Project: JBoss Messaging Issue Type: Bug Affects Versions: 2.0.0.beta4 Environment: Windows Vista-32 bit Reporter: Bijith Kumar Assignee: Tim Fox Priority: Critical Attachments: Sender.java As per the JBM documentation, if a client is idle (i.e. not sending/receiving any message), it will automatically send "ping" packets periodically to prevent the server from closing it down. So my understanding is that, the server should not close the connection as long as client program is running (e.g. just looping in an empty while loop). It seems this pinging is not happening always. Because, in my case, client program sends some messages and sits idle for 5 min and server closes the connection after 2-3 minutes saying "no ping received". Please see the complete server message below.

It sends 5000 messages to the Queue and idles for 5 minutes (just loops in an empty while loop) before exiting. Please find test instructions below. 1) Update JMX_URL, HOST and PORT in the attached Sender.java file according to your env 2) Compile and execute Sender.java a couple of times 3) Observe that the Server closes connection after 2-3 minutes printing WARNING messages shown above. If you are not able to reproduce it this way, try sending more messages so that paging starts in server, that would definitely reproduce it. I was able to reproduce the issue both ways (i.e. paged or not paged). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
