With 3.4.0, brick processes make use of ports from 49152 onwards 
(instead of 24009). Do you per chance have any firewall rules that can 
cause disconnects?

Nothing much to glean from the logs apart from the fact that there are a 
bunch of annoying ENOENT messages in the bricks. Can you change the log 
level to DEBUG and see if you notice anything amiss there?
