What does "deleted from unreachable cache" mean?

Due to a little too aggressive firewall configuration we had a lot of 

"deleted from unreachable cache"

messsages in the log, but absolutely no messages logged for the reason for entering the host
into the cache, which is much more useful in tracking down the problem.

It appears to me, that there is an asymmetry here, which should be fixed.

Our logging is configured as

	category queries { queryfile; };
	category dnssec { dnssecfile; };
	category security { securityfile; };
	category notify { queryfile; };
	category xfer-in { queryfile; };
	category general { queryfile; };
	category client { debugfile; };
	category unmatched { debugfile; };
	category resolver { queryfile; };
	category default { queryfile; };
