Is there any related log entries on the server at this time?
Each document is limited to much less than 16MB (8MB if I remember
correctly) so you can't have an array, or any value in the doc, which
will exceed this for any given emitted key (the group by part on the
emit call). Do you expect that you are trying to do this by creating a
large array? If so, can you create multiple emitted documents during
the map phase to break things up?
