@ShafeerAli Could you please attach your input document here for testing? We will check the issue and provide you more information.

Please note, 6k pages MS Word document is an extremally huge document and even MS Word not always can process such documents. But all depends on the inner document content. If such document consists of pure textual content, I doubt , that either MS Word or Aspose.Words can process 6k pages document with pure text. Please see our documentation to learn more about Aspose.Words memory requirements:
