Dan Smith commented on GEODE-370:
---------------------------------
I was able to reproduce this by sticking some breakpoints in the right places.
What's happening is this:
# serializer 5 is registered on server 1. It's sent to server 2 as a
InternalDataSerializer.RegistrationMessage
# The message is a PooledDistributionMessage, so it runs in a thread pool on
server 2
# serializer 6 is registered on server 1. It goes to server 2
# serializer 6 gets added to the client queue first, which serializer 5's
thread is still running
# serializer 5 gets added to the client queue, but the message is dropped
because the eventId is less than the last seen event.
