[atlas] Probe is down but does send DNS according tot SOS history

Hi, How can it be that the status of a probe is down while I see current DNS requests in the SOS list without any remarks in the 'info' column? Even the power-up time is increasing. If the probe can send DNS requests, why does it not have some mechanism to recover? Seem not too hard to make it reboot if it's status is down. Thanks, Dave
