Hi Tom, I finally tracked down the issue! The query that was generating the temp table which was used as input into the 2 cursor queries was generating an invalid, very large geometry (like 200mb). It turned out I had a bug in the previous testing I was doing, and I didn't actually remove the geometry column from the second cursor. So I guess a 200mb geometry being cast to text used too much memory. Not sure if there is still a leak... But I guess that depends on weather the geometry expands to over 1 GB when converted to text. Anyway I would like to personally thank you for you time in helping me with this issue.
