> The resource clean up code for dead clients doesn't seem to work reliably.
> Probably not a show-stopper for a beta release, but definitely needs to be
> cleaned up for production. Basically, when Artemis detected a dead client (it
> stopped responding because I hit a breakpoint in my debugger), it tried to
> clean it up, but failed. The result is that I can no longer connect a new
> client from that client machine, because the broker thinks I already have a
> connection. This is after I killed my client app and restarted it. I'll log
> a bug for this one, but here's the server log (note the final INFO message of
> "failed to remove connection"):
> {noformat}
> WARN [org.apache.activemq.artemis.core.server] AMQ222067: Connection failure
> has been detected: AMQ119014: Did not receive data from
> /xxx.xxx.xxx.xxx:53516. It is likely the client has exited or crashed without
> closing its connection, or the network between the server and client has
> failed. You also might have configured connection-ttl and
> client-failure-check-period incorrectly. Please check user manual for more
> information. The connection will now be closed. [code=CONNECTION_TIMEDOUT]
