> When a locator is restarted & recovers from disk it will try to take over the 
> role of membership coordinator for the cluster if it finds the current 
> coordinator is a cache server.  If the cache server is in the process of 
> sending out a new view it may get into a race with the locator in sending out 
> view preparation messages.
> The locator will send out a view-prep message and the server will also send 
> one.  Responses to the view-prep message will include the conflicting view 
> and each of the two processes will create a new view and send it out.  This 
> repeats ad-infinitum.
> This problem was observed in a system that was shutting down at the same time 
> a locator was being restarted.
