 This log message appears whenever validation of TSIG fails for some
 reason:

 {{{
 2011-10-26 12:35:52.460 ERROR [b10-xfrin.xfrin] XFRIN_XFR_TRANSFER_FAILURE
 AXFR transfer of zone example.com./IN failed: TSIG verify fail: FORMERR
 }}}

 However, the FORMERR is misleading. In this exact case, the signature was
 missing completely (because it was a servfail), but AFAIK it happened at
 other situations as well. It should tell more details.
