When the Linux kernel
processes a NTP add second or delete second event, it may suffer a deadlock while trying to log an
informational message. The chances of this may be greater when a system is busy.
All active X-Series releases use a vulnerable Linux kernel version.
Disable NTP at least 24 hours before the date of each upcoming leap second (e.g. June 30,
2015). Wait a day after the leap second and then re-enable NTP.
