Yep finally there’s something fishy. For some reasons it has problems with the timestamp.

Although the log entries been quite old there was none from today when I let npcd run for a while.

I don’t know why this happened, because the system time is correct.

I deleted the rrd files from spool and now npcd runs without pushing systemload into orbit but the graphs still show nan
