Apex heap size too large (when querying less than 1500 records) in a table

Hmmm … agg models isn’t an issue then. At least I don’t think so. Heap size is based on the size of the records package. # of fields per record affects this greatly.

The Order By w/ 2 fields also shouldn’t be an issue.

Honestly stumped since a query that should return less records is an issue and the a query that should more records isn’t an issue.
