-----------------------------------
Summary: Dead client resources are not cleaned up
Key: ACTIVEMQ6-107
URL: https://issues.apache.org/jira/browse/ACTIVEMQ6-107
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 6.0.0
Reporter: Jim Gomes
Priority: Critical
Fix For: 6.0.0
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"):

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.

Attempting to run a fresh client gets the following return exception on the
client:
