Nested Loops

I'm running ReadyAPI 3.64.0 and I'm running into a problem.  When I run a specific request, I get the following error:  

Thu Jan 22 10:27:26 MST 2026: ERROR: java.lang.OutOfMemoryError: UTF16 String size is 1074003966, should be less than 1073741823

Has anyone seen this before?  Is there a solution?  Does anyone have a workaround?
