Although a reload takes 0.02 seconds, a restart still only takes
0.3 seconds, which is so quick our NASes wouldn't even notice. I
wouldn't worry about it.

I've found out why only one of our servers is affected - the other
two have an old init script that don't implement reload, which
means logrotate hasn't actually been restarting the daemon... :)

So that seems to indicate it's the HUP that causes the problem.
