I get many alert with BoxDown 0 d, 00 h, 00 min Sysname IP From To Downtime boxState XXXXX.hivolda.no 158.38.XX.XXX 02:54 18-03-05 02:55 18-03-05 0 d, 00 h, 00 min boxDown

I believe this is due to some debug code that was unfortunately included in a beta release which sets the default wait time for event engine to a very low (5 seconds) value. You can fix this problem by uncommenting the line in eventEngine.conf which sets the alertTickLength (default is 60 seconds) and restart event engine. Note that there should not be a semicolon at the end of the line, so if there is one remove it.
