Closest thing I got to working involved "rolling restarts" of all nodes in a cluster with the connected clients running failover-semantics... this caused the issue a few times but not consistently _at all_ and the overall setup was to chaotic to make anything useful of it regardless. -- This is an automated message from the Apache Git Service.
