Thank you in advance for looking into this problem.
We are running a large report, over 100,000 rows, and I get a 500 error message. Things were working fine until we reached the 100K threshold. I have modified the report row limit to 150,000, but I am still getting the "500 error, page not found"
Note that I can display the rows OK on screen, but when I try to download as CSV, that's when I get the error.
