Hi Martyn, good Monday. Unfortunately, I've an update about our tests on artemis snapshot 1.6 you g= ave me last week. It seems that after few time of use (sometimes an hour ...other times less)= it stops to accept connections. Resources on server are totally ok: we hav= e about 40/50 clients, each one who sends 2/3 messages per minute., and cpu= and mem consumption is really low. But I don't know why... at a certain point, clients can't connect any more = to the Artemis broker. And I don't see any error on log (set to DEBUG level= ). Simply, whoever try to connect, stays in "CONNECT" status forever (perfo= rming retry attempts). I've done a thread dump of JVM in that situation: you can find it attached. You can see there are few threads that are BLOCKED, waiting to = lock at "org.apache.activemq.artemis.core.protocol.mqtt.MQTTConnectionManag= er.connect". I don't know if this can help to find the problem. Unfortunate= ly I'm not yet able to identify the exact steps to reproduce it. I'm curren= tly committed exactly on this. I'll let you know as s threaddumps.tdump <http://activemq.2283324.n4.nabble.com/file/n4721908/threaddumps.tdump> oon as I can.
Meanwhile: have you any idea? Francesco -- View this message in context: http://activemq.2283324.n4.nabble.com/ARTEMIS-bad-performance-behaviour-after-7-10-days-of-usage-tp4721272p4721908.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
