What I have done: I have restarted mysql on the JOINERNODE to apply some database settings including increasing the back_log and query_cache_size settings.
What I am seeing: When I start mysql on the JOINERNODE, I see socat launch and listen on port 4444 then stop about 1-2 seconds later.
Joiner MYSQL logs:
