Attached is the corrupt file. if i try to read the corrupted file using pdfreader i get the error message saying "start ref not found". But the issue is that problem is not consistant. I am able to water mark the same original file 2nd time using the same code. So it's like randomly some file is not fully written.
i am gussing this is because the pdfstamper is closing the memory stream earlier than it should for some reason. However what i want to confirm is that my understanding that the probelm is infact the memory stream is right or not?. Because i have implmented alternative technique to compltely avoid memory stream and pdf stamper but use pdfwriter and file stream which seem to have fixed the issue in dev. But still need to get response from a heavy testing team. Any light thrwon on this subject will be of great help to me.
