Hi all,

Sometimes the output from check_ntp_time is "Offset unknown" while the ntp
server is fine.

It can stay like that for a while and then comes back to normal.

Here's a sample output while the problem was present on the server:

*[root at bravura plugins]# ./check_ntp_time -v -H windows.foo.com*
sending request to peer 0
response from peer 0: offset 1.376408458
sending request to peer 0
response from peer 0: offset 1.375704885
sending request to peer 0
response from peer 0: offset 1.375001431
sending request to peer 0
response from peer 0: offset 1.374346972
discarding peer 0: flags=3
overall average offset: 0
NTP CRITICAL: Offset unknown|

*OS:* Red Hat Enterprise Linux Server release 6.2 (Santiago) 64-bit
*nagios-plugins:* check_ntp_time v1.4.16-29-g3c10 (nagios-plugins 1.4.16)

Any ideas?


Regards,
Ruslan
