Also appears to affect 6.3. The cause is: for bug 1564087, we set the global connection overall connection TTL for connections in HornetQ/Artemis to 24 hours. However, in HornetQ 2.4.7 (in 6.3) and Artemis (Candlepin master), the "invm" connection type that we use does not use a connection ttl by default, and does not behave well when it is set globally.
