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.

For those affected, jumping with the date command can be accomplished with:

     date; sudo date `date +"%m%d%H%M%C%y.%S"`; date;

One additional note, if this is a virtualized machine make sure to check the host server it is running on as well for the issue, it was the cause for us.
