Hi,

I've one dual-opteron machine in a 'soft production environment' :) as a 
ntp *client* and so far I can tell that it is not panicking, if this is 
what you want to hear. It is synchronized to one local ntp server, the 
message you mentioned I can see aproximately once per hour, system is 
NetBSD 2.1_RC6. The current uptime is not very big, but you can get the 
picture:

$ uptime
  1:53PM  up 5 days,  5:21, 1 user, load averages: 8.58, 8.59, 8.67
$ ntpq -p
      remote           refid      st t when poll reach   delay   offset 
  jitter
==============================================================================
*our.local.ntp.server 195.113.144.201  2 u   89  128  377    0.135 
-17.857  14.012
$

I have been told that the message 'could' indicate a hw problem.
