Unfortunately ntp debian package is compiled using configure 
--disable--debug so I can't debug it
and I can't have a core dump.
My configuration is:

NTPD_OPTS='-4 -g -I eth0.118'


driftfile /var/lib/ntp/ntp.drift

# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/

server 1.debian.pool.ntp.org iburst
server 2.debian.pool.ntp.org iburst
server 3.debian.pool.ntp.org iburst

restrict -4 default kod notrap nomodify nopeer noquery

version of ntp is 4.2.6.
