Comment (by jrfoell):

 I just want to upvote @jipmoors batch patch. I was getting intermittent
 500 errors because of out-of-memory on this very issue. 130 custom post's
 meta (with apparently **a lot** of meta) were trying to be cleared. I
 actually had to reduce the batch count from 250 to 100 to get it to fit in
 memory (150MB).

 I would suggest that maybe this value should be changeable via a filter.
