Here are potential causes of MLCCC cracking, and how to tell what caused
the crack based on the crack's position, run direction, etc.

http://www.syfer.com/category_docs/AN0005_Mechanical_Cracking.pdf

And an authorative paper on the subject by John Maxwell, who I think
knows more about root causes of cap cracking than anyone:

And a potential solution to the problem:

Qualify it first.

Well, in the case I was asking about none of the failures were in that
direction (across the body) but always along it splitting both ends in
half either vertically or horizontally. Still a puzzle to me :-)

So they were cracking normal to, not along the body of the caps. Right?
