Generating a Qlik NPrinting report with an output of more than 512MB will fail with:

ERROR: System. IO .IOException: Stream was too long.↓↓ at System. IO .MemoryStream.Write(Byte[] buffer, Int32 offset, Int32 count)↓↓ at Ionic.Zip.CountingStream.Write(Byte[] buffer, Int32 offset, Int32 count) 



Since the November 2020 release, RabbitMQ Server (deployed as Qlik NPrinting Messaging Service) has been updated to version 3.8.3. It has an internal limit, not configurable, about messages size of 512MB. Previous limit was 2GB. As consequence, is not possible to generate Qlik NPrinting reports bigger than 512MB.

See Report size limit | Qlik NPrinting Release Notes.
