It's a bug in the client handler. The reason why it happens for one hour
every day is that the "uptime" output is different for that hour. Most
of the time, it looks like

 08:26:57 up 4 days, 10:22,  3 users,  load average: 0.01, 0.10, 0.06

but for one hour each day - starting N*24 hours after it was booted - 
it will be

 08:26:57 up 7 days, 13 mins,  3 users,  load average: 0.01, 0.10, 0.06

which the 4.1.1 version of hobbitd_client fails to recognize.


I really need to get 4.1.2 finished ...
