I can appreciate that, but when emc nor rtai are not running? It is ATM, and I just did an ./ntp restart to see if any errors came out, there were none, and the date on that box is to the second synced with this box. So I don't /think/ that is the problem. ntp these days may do a crash set call to ntpdate at bootup on most systems, but IIRC it now uses a similar call to what 'adjtimex' does, which diddles the count per second, which if the mobo crystal is on spec, 10000/sec. I have had mobo's that I had to set it for 9998 in order to get it within reach of ntp keeping it there. But ntpd itself is now using a wider ranging method albeit it is still tuning the oscillator by only 1% maybe. Its control hasn't had discrete time jumps in 2 or 3 years now. I think the point is that when the updater runs, it apparently must be doing something that I, as root, cannot trigger in normal use, so I am inclined to point fingers at the updater, not ntpd. > Jon > > ------------------------------------------------------------------------ > ------ Got Input?
