While I understand you may not be allowed to update your
production systems to a current kernel and current ntp;
Have you tried current versions on a test system,
to see if the issue has already been fixed?
Then you could just research the changes,
and see if you could make your system avoid? the issue
until you can upgrade to a version that no longer has the issue.
