Luis Miguel De Bello updated ARTEMIS-2991:
------------------------------------------
Description:
We are running Artemis 2.9.0 and we noticed the memory grows continuously after
getting a heap we discovered there are a leak of multiple instances of type
org.apache.activemq.artemis.core.remoting.impl.netty.HttpAcceptorHandler which
are keep in a list inside
org.apache.activemq.artemis.core.remoting.impl.netty.HttpKeepAliveRunnable.
Those instances are removed in the channelInactive method but this method is
not called because when doing the upgrade to websocket the handler is removed.
Proposals:
1) In the upgrade clean up the reference for the HttpAcceptorHandler before
removing the handler.
2) If option 1 does not work because that threads also send the keep alive for
websocket, I could use the channelInactive from websocket handler to later
unregister the handler
