I believe the rehasher actually does do this. Do you have a test that consistently
reproduces this?

I can reproduce something similar every time. With the latest 4.2.x
git, if I wait for each node to initialize before starting the next everything is fine:
with an empty cache the time to start each node is in the order of a couple of seconds. If
instead, I start two or more nodes at the same time, Infinispan seizes up for a much
longer time. In the worst case I have seen Infinispan time out after 20 minutes. I can
provide exact traces (I am not on my work computer at the moment), but I think that the
rehasher should queue up other nodes while it is busy rehashing. This is quite a serious
issue in my opinion and we should try and fix it before CR.

Sorry, I mean to say that "I'm pretty sure this is NOT a network issue".
It might be mitigated that way yeah, but it'd be helpful for you to help us adding
some TRACE logging for org.infinispan and attaching the startup log files of all parties
involved if you can replicate the issue easily.
