	There was a attempt to return more objects to the pool than
	had been allocated.

	Errors like this should be reported to bind9-bugs at
	along with a stack backtrace, compiler used (including version)
	options used to compile named, location where the executable
	and core dump can be fetched from and anything else you feel
	is useful.
