Dave;
I suspect that you've identified the cause in your comment below. Shock loading as the boom hits the end of the swing following a gybe (According to my copy of the International Marine Dictionary a "jibe" is a sudden or uncontrolled shifting of the boom from side to side due to steering error or sudden wind shift.) can pull the sheet out of a pretty stout cam cleat. Been there, done that. My setup has a Garhauer fiddle block on the traveler (with the cam cleat jaws pointed down so the mainsheet trimmer has an easy and natural motion of lifting the line to cleat it - and can step on the line to release under heavy load). When gybing the normal practice is to pull the boom in near center and then release and ease the sheet out to proper trim as we finish the gybe. When single handing, I can pull the sheet in from the helm before the turn and ease after settling on the new course. When racing, there is a mainsheet trimmer to do the adjusting of mainsheet and traveler during the turn. Since I've started doing this I can't recall a sheet pulling loose unexpectedly. BTW, I have a 3:1 arrangement on the end of the mainsheet at my bridge deck traveler, and 5:1 purchase for the Garhauer traveler.
