      Hi,

      We have this issue where there is an unexplained huge jump in Value Cache hits in which we then experience a build up in the History cache until we restart the server. This happens regularly ie every week or two.

      I have included several graphs for the last 7 day period. Clearly you can see at approx 2-3pm yesterday there was a massive jump in value cache hits without a massive jump in monitoring configuration and the history cache starting to rise at the exact same time.

      I have attached several graphs which show this value cache hits, process performance, cache capacity, value performance and monitoring configuration graphs. 

      Regards

      James
