Quick follow up on this - Was this bug fix implemented in 2.8.7 or something later, i.e. 3.0?<br><br>I think I'm running into this again when shutting down a set of bi-directionally federated brokers. It appears when a broker shuts down, it wants to reach over to the other broker to clean up something (federation queue?)<br>
<br>If the other broker has already shut down, the currently shutting-down broker will stall for a very long time (e.g. 15 minutes or more.)<br><br>Thanks,<br><br>Matt<br><div class="gmail_extra"><br><br><div class="gmail_quote">

Quick update for you Matt. I was able to fully reproduce the behaviour you saw by dropping certain packets sent from the downstream federation client to the upstream broker during connection.close. We filed a bug and have implemented a fix, which should appear in a forthcoming release!<br>

> Very much the latter at the moment. We've filed a bug to investigate and I'm going to apply some specific packet filtering during shutdown to see what kind of impact a lost FIN/SYN might make. I'm also going to be reviewing the supervision hierarchy in the erlang client (which federation uses) to see if there's and shutdown/timeout choices that aren't quite right.<br>
