Hello.
As you might know, on July 1th, 2012 time was changed to 1 seconds back, which affected some NTP-enabled systems.
Symptoms are server lockup and high cpu usage for some processes.
We've got reports about Debian6 and Ubuntu12 servers running nxagentd.
Fix:
* Upgrade tzdata packages
* Either reboot server or stop ntpd then set date manually and then restart ntp and affected applications
UPDATE: looks like it's enough to just jump time a couple of seconds ahead using "date" command, no need to restart anything. Ntpd then will resolve this jump.
Also please check Marco's blog for more details.
