The issue we are encountering in that when making an HTTP Request, we immediately receive an System.CalloutException: Exceeded max size limit of 3000000. This issue is not occurring with the same code in the org's sandbox. In the sandbox, the call is successful and returns data as expected. But in the production instance, we constantly receive this error. I have checked the heap size prior to making the callout and it is 5406 bytes in size, well within the 3MB size limit. This is being reported in both the sandbox and in production. All other governor limits are well within limits. There are two HTTP requests that are made before the call that causes the error (to authenticate, etc.) so it is very confusing why this error is occurring, especially since it works just fine in the sandbox.
