Acrobat High RAM usage (90%+)

Hello,

 

I am currently experiencing issues with Adobe Acrobat using 20+ GB of RAM when trying to use any acrobat functions from organizing pages to OCR. These are not large files (>100MB). I’ve been able to consistently reproduce the issue with multiple different files and on multiple devices including PCs fresh out of the box. 

 

I have reproduced the issue on W11 24H2 and 25H2, On Acrobat Version 25.001.20997. Tested it on both 32 and 64bit. Uninstalled and reinstalled acrobat. Tried doing a full reinstall of the computers OS. Protected mode is disabled. 

 

Systems have 32GB of DDR5 RAM, an i7 with an M2 SSD.

 

It seems like from my research this is just a consistent issue with Adobe as I’ve seen reports of this same issue going back 10 years. Is there ever going to be a fix?

    I have you all beat and I’m just using acrobat to view and add comments to very simple pdfs. 513.53 GB of virtual memory in use.

    Hello @WallabyMK


    I hope you are doing well, and thanks for reaching out. I’m sorry you’re running into this. Acrobat consuming 513.53 GB while only viewing and commenting on simple PDFs is clearly excessive. The screenshot confirms abnormal memory consumption, although it doesn’t by itself establish the underlying cause or confirm a memory leak.


    Save any open work, fully quit Acrobat, and restart your Mac. Please ensure you have the latest version of Acrobat installed on the machine: 26.002.21931, Out of cycle update, Sep 17, 2026. Check for any pending updates by navigating to Menu > Help> Check for Updates. Install the updates, restart the app and the machine, and try again


    After restarting, open Acrobat without a PDF and monitor it briefly. Then open one simple PDF at a time and check whether the memory usage begins increasing again.


    Uncheck Use Page Cache. Acrobat menu > Preferences (Cmd+K) > Page Display, under Rendering untick "Use Page Cache" (and "Smooth Images"), OK, relaunch. If it persists, quit stuck processes and repair. Activity Monitor > stop any AcroCEF/RdrCEF processes, then Menu > Help > Repair installation.


    I hope this helps, and please let us know if you experience any issues or need any assistance.


    Regards,

    Anand Sri

    Hi ​@Agabriel ,

    This caused me a lot of headaches, and in the end I had to restart Acrobat after every scan (it was using up to 250GB of virtual memory and would occasionally crash whilst I was editing pages). I disabled the AI features as a test (Preferences -> Generative AI). Since then, I haven’t had any more memory issues and Acrobat no longer crashes regularly, which used to happen. So if you don’t need the AI features, it might be worth a try.

    Hi ​@WallabyMK,

     

    Hope you are doing well.

     

    Sorry for the trouble with using Acrobat, and thanks for sharing the workaround. 

     

    If the situation occurs only when you are using Acrobat with Gen AI features enabled, would you mind helping us with the logs so we can investigate the issue better?

     

    If yes, please help us gather logs from your machine: https://adobe.ly/4l1gBRA. Please make sure Procmon is selected. You can upload logs using this tool and share your Unique log ID with us. 

     

    Look forward to hearing from you.

     

    Regards,

    Souvik

    Hi ​@Agabriel ​@WallabyMK,

     

    Thank you for your patience. 

     

    While the team is working on the issue, and the fix is to be released soon, please try the below registry codes as a temporary workaround:

     

    Go to Start > Registry Editor > location (depending on the system architecture)

    32-bit system: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Adobe\Acrobat Acrobat\DC\FeatureLockDown\

    64-bit system: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown

     

    Once there, create a Dword: bIsRenderingPerfImprovementsDisabled

    Value: 1

     

    Note: Please keep Acrobat closed while you do so.

     

    Let us know how it goes.

     

    Regards,

    Souvik

    Hi ​@Agabriel,

     

    Hope you are doing well. Sorry for the trouble with using Acrobat.

     

    When you mention files not being very large, are they files generated through DWG or AutoCAD, or are they design files? Just trying to understand the type of files you are working with to give a better solution.

     

    Also, did the issue start occuring recently or is it a persistent issue from a few updates?

     

    Would you mind sharing a few more pieces of infromation for further investigation:

    1. A sample file (if possible) to try and reproduce the issue in-house;

    2. Please help us gather logs from your machine: https://adobe.ly/4l1gBRA. Please make sure Procmon is selected. You can upload logs using this tool and share your Unique log ID with us. 

    While you do so, please try the below steps and check if it helps:

    1. Go to Preferences > Page Display > uncheck “Smooth Images” and “Use Page Cache;”
    2. Go to Preferences > Documents > Change the number to the right of “Documents in the recently used list” to anything 10 or below;
    3. Update the application to the latest version (25.1.21265). Info here.

     

    Let us know how it goes.

     

    Regards,

    Souvik
