CentOS 6.4, x86_64.
ntpd on one of my systems has started consuming 66% of one core, although it appears to be functioning correctly otherwise. No pertinent logs. Of course, nothing was changed :) I’ve seen this before many times, but usually the CPU consumption falls back to normal within a day or so, but this has been going on for several weeks now. Stopping and restarting ntpd makes no difference. Reinstalling ntpd makes no difference. The ntpd.conf file is the same as on 200+ other systems, all of which work normally. Anyone seen this before?
