Infinite Cache Cleaning

[Mark Olbert]

I just had a very odd Linux system lockup:  my syslog file
(/var/log/messages) was expanded enormously by a seemingly
never-ending series of 'cache cleaned' messages from named.

'Enormously' in this case means that the messages file grew to over 49
megabytes (!!!). I've never seen it bigger than about 250K before
this.

Needless to say, I'd like to understand what caused this problem so I
can prevent it from recurring.

Anyone have any experience with this problem?
