Weird messages output

[Eirik Øverby]

Hi all,

running 6.1-RELEASE on several HP DL385 servers (identically  
configured), one of them has recently spat the following out in the / 
var/log/messages file:

..........
Mar 10 03:51:24 apphost02 ntpd[445]: kernel time sync enabled 2001

Mar 10 06:08:01 apphost02 ntpd[445]: kernel time sync enabled 6001
..........

NMI = non-maskable interrupt, if I remember correctly. However, I  
have no idea what this means or why it appeared. The status light on  
the front of the server has lit up red, as opposed to the usual  
green. All services on the host are running and behaving normally  
from what I can tell.

Any input, anyone?

Thanks,
