The default in /etc/ntp.conf on wheezy is:
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery

On wheezy I adjusted the ntp.conf like you said:
$ grep limit /etc/ntp.conf | grep -v ^#
restrict -4 default kod notrap nomodify nopeer noquery limited
restrict -6 default kod notrap nomodify nopeer noquery limited
Checking with check_ntp_time binary from the soon to be released next
upstream:
$ /usr/lib/nagios/plugins/check_ntp_time -H localhost
NTP OK: Offset -0,0002338594495
secs|offset=-0,000234s;60,000000;120,000000;
$ dpkg -l | grep monitoring-plugins-basic
ii monitoring-plugins-basic
2.0+git20141006-1~2~bpo70+1 i386 Plugins for nagios
compatible monitoring systems (basic)
Even with the check_ntp_time binary from the 1.4.16-1 it seems to work:
$ /tmp/check_ntp_time -H localhost
NTP OK: Offset 4,751665983e-06 secs|offset=0,000005s;60,000000;120,000000;
$ /tmp/check_ntp_time -V
check_ntp_time v1.4.16 (nagios-plugins 1.4.16)
Unfortunately I can reproduce your problem. Maybe you can test my
latest packages for wheezy (see http://ftp.cyconet.org/instructions
for installing experimental monitoring-plugins packages from my
wheezy-backports repository). Even you can describe a bit more
specific your environment to reproduce this issue.
Many thanks, Jan.
