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.
That's news to me -
