On our setup, the problem comes from a counter overflow in uptime
handling on some SCO : after 248 days of uptime, the uptime is reported
negative, and the rrd handler misses the expression (no "up:").
Ahh - the old 31-bit timer tick issue. Linux has the same problem
because a timer ticks at 100 Hz using a signed 32-bit integer; so
2^31 / (24*60*60*100) = 248 days and a bit.
Reboot of the system solves the problem :).
Add
	UP 1h 240d
to hobbit-clients.cfg to get a reminder 8 days before it happens.
