[jboss-jira] [JBoss JIRA] Closed: (JBAS-5468) when the shutdown of the server is complete, some ports still been used (timing issue)

[Adrian Brock (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBAS-5468?page=all ]

Adrian Brock closed JBAS-5468.
------------------------------

    Resolution: Rejected

This is NOT a JBoss issue.

1) When JBoss shutdowns it tells the Coyote connection to stop which closes the port
2) The "HALT" shown terminates the process which means the OS should close the port
anyway (even if JBoss didn't do it explictly).

To test JBoss is doing it correctly, I chose the harder problem of undeploying JBossWeb
on a running server. i.e. not process termination to catch a missing ServerSocket.close()

[ejort at warjort bin]$ cd ../server/default/deploy/
[ejort at warjort deploy]$ mv jboss-web.deployer/ ~/temp

12:21:37,936 INFO  [Http11Protocol] Pausing Coyote HTTP/1.1 on http-127.0.0.1-8080
12:21:37,937 INFO  [AjpProtocol] Pausing Coyote AJP/1.3 on ajp-127.0.0.1-8009

12:21:38,985 INFO  [TomcatDeployer] undeploy, ctxPath=/web-console, warUrl=.../deploy/management/console-mgr.sar/web-console.war/
12:21:38,986 INFO  [TomcatDeployer] undeploy, ctxPath=/jmx-console, warUrl=.../deploy/jmx-console.war/

And port 8080 is no longer open
[ejort at warjort deploy]$ netstat -an | grep 8080
[ejort at warjort deploy]$ 

Showing JBoss is doing it explictly/correctly.

If the port is still open then the underlying OS must have a reason for not closing
immediately when JBoss requests it or terminates.
