Ah, I understand! Thanks! :-)

Actually the solution is to split the underlying OCL query into smaller
blocks, which I've already done and it works fine. It just would have
been nice to have a crystal clear limit to put into my code that does
the split. Oh well, as long as it works and I know why...

Thanks a bunch Ann, as always!
