Ok, thanks for confirming! Is it normal, that this action affects the overall state of the cluster? On the 26th It started the regeneration and the the response times of the cluster raised to never seen values. It was a day of heavy traffic but everything was going quite ok until it started the regeneration process..
Have you got any advices about changing those app.config values? My cluster is running smoothly for the past 6 months and I don't want to start all over again :) Best Regards On 27 December 2013 18:56, Matthew Von-Maszewski <matth...@basho.com> wrote: > Yes.
