Hi 
 We had some problems on Monday relating to an application control update. In some cases this caused the http proxy to create coredump files in /var/storage/cores and these can potentially be quite large. If you take a look in that directory and check the modified date on the files named beginning with "httpproxy.NAVLWorker_" 
 If they are all from the beginning of the week and no new files have been created since then they can be safely deleted to free up the space. The issue itself was resolved quickly via a data update.

Hi 
 You can clear all the files from that directory if you like. Their only purpose is to aid in diagnosing problems, so if they are all old, or we already know the cause, they are no longer needed. You can see the httpproxy ones are quite large so that will almost certainly be the cause of your disk usage.
