I agree that you may be using too many parts during merge and prep so

if one part always stops the build try building it alone
but also...
verify each part
read message file
reduce the number of parts per build

if the part still fails....and I have seen this before. that one part may have
a small undetectable hole in the solid model. The verify software does not
always pick up such small holes. Usually this is seen when the same STL
data is used
to drive a milling machine.
