When trying to view a database revision, the FWM process generates *CPMILinksMgr.db* cache files for each database revision in *$FWDIR/conf/db_versions/databases/\* directory. Since the database is large, the *CPMILinksMgr.db* file is also large and this causes the connection to time out. ## Solution This solution requires authentication.
