[IRCServices] AKILL on * has expired

[CJB]

I apologize if this has been covered here before; I don't recall seeing it
mentioned.  I am noticing the following message show up a lot:

*** Global -- from OperServ: AKILL on * has expired

Nobody has akilled *, so I'm wondering if anyone might know what this is
exactly?  My only guess is that it may have something to do with the timed
akills set by the other U:lined server on the network (we have a secondary
U:lined server that sets akills on common drone/floodbot nicks, open SOCKS
and HTTP proxies, etc) and maybe the * is from the ident parameter of the 
akill.  As far as I can remember, I only recall seeing these messages
after upgrading from 4.5.24 to 4.5.29.

I am currently running ircservices-4.5.30 and bahamut-1.4(30).

Thanks.
