Does this box have NTP running, and is it perhaps drifting out of sync then
being corrected by a large (relative) value?  I recall seeing a note either
on the issue track on SVN logs about a recent fix to make internal_timing
less sensitive to time changes.

I know I broke a box a couple years back by manually updating the time on
a box that had drifted a couple minutes out of sync.
