[ntp:questions] Time slew doesn't seem to work

Hi,

I've started ntpd with the -x option and defined at run-time (using ntpdc) 3
servers. The client machine has an offset of +/- 2s with the ntp servers.
In the NTP log file I find the following statements (extracted out of a
total of 98):

9 Apr 07:46:13 ntpd[19257]: time slew 1.781571 s
9 Apr 08:01:16 ntpd[19257]: time slew 1.781200 s
9 Apr 08:17:21 ntpd[19257]: time slew 1.781085 s
9 Apr 08:32:33 ntpd[19257]: time slew 1.781807 s
9 Apr 08:48:37 ntpd[19257]: time slew 1.782273 s
9 Apr 09:04:38 ntpd[19257]: time slew 1.781004 s
9 Apr 09:19:42 ntpd[19257]: time slew 1.781344 s
9 Apr 09:34:46 ntpd[19257]: time slew 1.780407 s
9 Apr 09:49:50 ntpd[19257]: time slew 1.778824 s

The times don't seem to converge.

When I shut down the ntp daemon and try to slew the time using ntpdate with
the -B option it does work. The time difference with the ntp servers
gradually declines.

We use Suse SLES10 (kernel version: 2.6.16).

Does anybody have an idea on what's going wrong?

Thanks,
Jan
