Hi all,
We are getting intermittently a "[actor name [joinSeedNodeProcess] is not
unique!]" exception at the akka Cluster system start up.
The production setup is a akka Singleton cluster deployed on 12 tomcats across
3 physical machines (4 nodes on every machine).
Do you have any idea how we could fix this?
Many thanks,
Ryadh
