After (an apparently) succesfull startup, I see DEBUG messages related to joinSeedNodeProcess and firstSeedNodeProcess telling that both actors probably have been stoped.
I would like to know if this is and error, and if so, what would be causing it.
Bellow some INFO and DEBUG messages after starting the cluster:

Resolve (deserialization) of path [system/cluster/core/daemon/joinSeedNodeProcess-1#-1072938064] doesn’t match an active actor. It has probably been stopped, using deadLetters.
