The size of the response is what seems to be causing the second query -- 6 or more seems to be the trigger. My initial guess was that the first lookup led to an ERANGE internally, resulting in the second query, but that should have happened for 32-bit as well. So this might well be something else. This has nothing to do with whether there is a CNAME in the response. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
