Uptime is over 4 days, but graphs end about 22 hours ago. I was not in the web UI or on the console/ssh at that time.

Hi,

I've encountered this problem as well, both in 1.2.2 and 2.0. When I go and look at the processes running, I find two /var/db/rrd/updaterrd.sh processes running. If I kill one of them manually, the rrd process starts recording properly again.

Not sure how this come about; seems random.

This keeps happening, twice in the last day, and across 2 versions (BEAT 5 and the current one listed at top). On BEAT 5 it recovered with no user intervention. It's possible the CPU was maxed out at that time though, and I think I've seen graphing quit when the CPU is under load. This most recent outage occurred at a time when there should have been plenty of CPU cycles to go around.

when that happens, check for updaterrd processes, and check the system log for anything rrd-related.
