Possibly, and maybe even likely. I am not sufficiently familiar with erlang distributed 
mode and rabbit internals to say what kind of failure could lead to results that you 
described though.

Are you sure there is nothing of interest in rabbit logs, apart from timeouts, on both 
instances? Maybe something in system logs?

Any info in client logs maybe that could explain why all of them connected to a single 
broker (I assume normally you spread connections somewhat equally between the 2 brokers)?
