    Hi, thank you for reaching out.

    I have some additional information that may be helpful.

    For my current project:

    * Number of linked images: approximately 3,000
    * Total size of linked image files: approximately 430 MB
    * Illustrator (.ai) file size: approximately 384 MB

    The file contains only placed linked images. It does not contain any vector paths, text, clipping masks, effects, symbols, patterns, or any other Illustrator objects.

    When I first open the file, Illustrator uses around 3 GB of memory. After that, the memory usage gradually continues to increase over time, even if I leave Illustrator idle without doing anything.

    Compared to my previous project, this file actually contains less data. I also tested opening only this single file with no other Illustrator documents open, and the same behavior still occurs.

    In contrast, I have not observed this issue with files that contain only vector artwork and no linked images. If there is any memory increase in those files, it is so small that I have not noticed it during normal use.

    The issue is also not specific to this file. If I create a new document containing a similar number of linked images, I get the same result.

    Regarding the debug session, thank you for the offer. Unfortunately, I'm very busy with work at the moment, so I don't think I'll be able to make time for a live debugging session. However, I'd be happy to help through chat by providing additional information, collecting logs, testing builds, or trying any troubleshooting steps you would like me to perform.

    Thank you for looking into this.

    Thanks for your suggestions!

    I don't use any third-party Illustrator plugins.

    I do use several scripts, but they worked without any issues in Illustrator 2025 under the same environment.

    I also checked the GPU issue you linked, but the problem still occurs even with GPU Performance disabled.

    Memory usage keeps increasing over time, and closing the document doesn't release the memory. The only way to recover it is to restart Illustrator.

    So it seems to be a different issue.
