Folks, Just wondering what other sites do when the client cache gets filled up and the users can't launch a new application that's not already cached? On my future machines I may have as little as 4gb of cache space (limited disk space) with about 40 applications softgrided which would total more than 4gb. On my test system I have found that the cache doesn't automatically release space to allow the new application to run. I'm probably missing an optional setting though? Any advice received with thanks, Martin Searle Computing Service University of Kent.
