The xntpd daemon might die for several reasons. E.g. it might die if the server's time differs too much from the timeserver's time. You could try this:
Kill the xntpd process from the processlist.
Make sure that the server's date and time are about what it should be.
Make sure that xntpd can reach its timeservers as it/they are configured in the /etc/ntp.conf
startsrc -s xntpd
Check synchronisation with: xntpdc -c peers
Check xntpd status with: lssrc -ls xntpd
Subsystem xntpd should stay active.
