So, as of last Sunday all java servers in my park started running at 100% CPU capacity. Turns out there’s a leap second bug in current java releases on Linux servers.
I found this post where a temporary workaround/fix is provided.
Run these commands, and the load should start declining right away:
/etc/init.d/ntp stop date `date +"%m%d%H%M%C%y.%S"`
