This is usually caused by faulty hardware or firmware. See:

http://bugzilla.mindrot.org/show_bug.cgi?id=845

The fact that it occurs sending large emails but not receive them seems
to indicate a problem with the outbound path so I'd check network
components first.

usually comes from bad judgement.
