Coincidentally I fixed this earlier this week on one of our rancid instances.

In the file 'arrancid' look for the section '# This routine parses "dir flash:"'
and add the following line(s)

+	# Ignore debug subdirectory
+	/drwx.*debug/ && next;

before it invokes the function 	
	ProcessHistory("FLASH","","","!Flash: $_");


Apparently newer EOS versions such as 4.27 are now frequently touching the debug 
directory in the filesystem.
