I have a unit test demonstrating this issue but don't see any obvious way to attach files to the JIRA isssue.

> If a stomp client is receiving server pings and subsequently stops responding to the pings without gracefully disconnecting, the server keeps attempting pings indefinitely even after the connection is closed.  If this happens with many clients it will continue to consume server resources and fill the server log with warnings:
> 14:33:20,878 WARN  [org.apache.activemq.artemis.core.protocol.stomp] AMQ222068: connection closed org.apache.activemq.artemis.core.protocol.stomp.StompConnection@18a45f2e
> This problem can be easily reproduced by creating a Stomp client that initially responds to pings but then stops responding, for example by stopping the client thread responsible for handling the server pings.
> The only solution is to restart the server to clean up all of the ping attempts.
