Indeed, it's a bug in net-snmp regarding 64-bit counters,
or rather, in its AgentX perl interface.

This is from amavisd-new 2.6.4 release notes:

  The setup was tested with Net-SNMP versions 5.3.2.3, 5.4.2.1 and 5.2.0.
  If you experience wild numbers served in Counter64 variables on a 64-bit
  platform, the following patch (at the server side) solves the problem:

    http://www.mail-archive.com/net-snmp-users@lists.sourceforge.net/msg19502.html

  The patch seems to already be incorporated into version 5.3.3 of Net-SNMP,
  and into 5.5 (but not in 5.4.2, nor in 5.2.0).


I don't have more recent information unfortunately.
Updated information on this bug resolution is welcome.
