Some systemtest (in enmasse.io) using a 2-router setup is causing one of
the routers to hang with no output. I'm unable to connect directly to the
router once it is in this state. I'm working to collect a core/thread dump
that contains symbols.

This is a deadlock in the timer systems caused by DISPATCH-1274. That optimisation assumes there will never be more than 256 timers. However if initialHandshakeTimeoutSeconds is set on a listener, there will be a timer created for every connection.

I'd suggest perhaps we consider backing out DISPATCH-1274 for now as it an optimisation rather than a crucial feature or fix.
