Francesco Padovani commented on ARTEMIS-1218:
---------------------------------------------
An update.
We have re-build "artemis-commons-2.1.0.jar", "artemis-mqtt-protocol-2.1.0.jar"
and "artemis-server-2.1.0.jar" in order to improve the logs. It seems that
there is a problem with the thread which has in charge the activities to free
the clientid, send lwt message, etc..
For a few time all works good. Broken connection are correctly cleaned and I
see all the logs related to the clientid cleaning and lwt sending.
Then, at a certain point (we've not yet undestood why...) connections are no
more cleaned correctly. And there are no more logs about the "cleaner" thread.
And there's no error. It seems like the connection.fail method simply is not
called.
logger.debug("connection id " + conn.getID() + " calling fail executor thread
"); flushExecutor.execute(new Runnable() {
public void run() {
logger.debug("starting thread for removing connection "+ pair.getA());
conn.fail(ActiveMQMessageBundle.BUNDLE.clientExited(conn.getRemoteAddress(),
pair.getB())); logger.debug("thread for connection "+
pair.getA() + " ended correctly"); }
...I can't see the log above. Have you any idea about the cause?
Thanks.
