Question

'Cos document table full' while using Comments

I'm working on a PDF which has a fair amount of mark up (mine) but I now can't add any more, or edit the mark up, because whenever I click on any mark up I get the error message 'Cos document table full'. It's started happening on a few of my PDFs now. 

When I've searched this issue, people seem to have problems if they're signing documents. There are no signatures in my documents, just mark up using the Comments feature. Please can someone help?

    Did you ever find a solution to this? I'm suddenly experiencing the same problem--unable to mark up using comments. Just keep getting the "Cos document table full" message.

    Unfortunately not! I tend to split the PDF into sections now if I know there will be a lot of mark up on it, which helps (although isn't ideal if you need to look at one complete document).

    Ok. I was just chatting with Tech support for about an hour. Turns out, in my case, there were restrictions placed on commenting by the creator of the document. So having to send it back to get the restrictions removed. One way to test is to see if you can add a comment to a new document that you created.

    Which version of Acrobat are you using? I've never seen this message. How many annotations do you think you have in the document?

    Hello,

    I've got approx 500 comments in it, and it's a 145 page document, including images. 

    I'm using Adobe Acrobat DC (21.007.20099).

    That is not a lot of comments, but it's certainly possible that the PDF file itself is highly complex (and therefore uses a lot of COS objects). I just had a script create about 3500 annotations in a document without a problem.

     

    The first thing I would try is to do a "Save As" on the document. When you do a normal "Save", Acrobat will save an incremental update. This means that the original file is being kept intact, and new or modified information is added to the end of the original file. If you have a lot of these incrementtal updates, you might fill up the space that is reserved for COS objects (but again, I've never seen this error message before, and I've worked with PDF files for a long time). Doing a Save As will recreate the document from scratch, and that might fix your problem. So, do a save as to a new filename, and then see if you can open this file and add more annotations without getting the error.
