When a downtime was configured to recur every hour and a 1h DST shift happened, the CMC would go into an infinite loop with 100% CPU load and no monitoring at all. If the downtime in question was set in an ad hoc fashion via the GUI (not via rules), the only way to work around this issue was to remove the state file, losing all downtimes, acknowledgements and comments.
