Acrobat standard memory leak on multiple devices in organisation

​Hi @hatshatahsththstst ,

Thanks for sharing the screenshot, and sorry you're running into this, especially on a brand new machine.

This thread has mostly been reported on Windows so far, so your case is a useful data point that this isn't platform-specific. In the Windows reports here, the underlying cause traced back to a background process called AdobeCollabSync (Acrobat's collaboration/sync helper for shared reviews, comments, and cloud file sync), which can balloon in memory under certain conditions. That process exists on Mac too, so it's worth checking directly.

A couple of things would help confirm this is the same issue: what version of Acrobat are you on (Help > About Acrobat), and do you use any shared reviews, document comments, or Adobe cloud storage/sync features, or is this a fully offline, local-files-only workflow?

Worth checking right now, since Acrobat is still open with high memory in your screenshot:

• Open Activity Monitor and search for AdobeCollabSync. If it's also showing unusually high memory, select it and force quit it specifically (not just Acrobat), then see if Acrobat's own memory drops afterward

• Go to System Settings > General > Login Items & Extensions and remove AdobeCollabSync if it's listed there, to stop it launching automatically at startup. Note that it can relaunch on its own when Acrobat opens a shared or commented file, and Adobe updates can re-add it

• In Acrobat, check the hamburger menu > Preferences > Documents, and clear "Show Online Storage When Opening/Saving Files" if you don't use Adobe cloud storage

• Check for a pending Acrobat update, go to Help > Check for updates, and reboot the computer once, and see if that works.

If force-quitting AdobeCollabSync specifically brings the memory back down, that confirms the same cause as the Windows reports, and extends this to macOS as well, which is useful to note here.

Let us know your Acrobat version and what Activity Monitor shows for AdobeCollabSync, so we can take it further.

Confirming the same issue in our Company.. reports from over 6 months ago. Windows 23h2 / 24h2. Case number E-001492887 was raised.
Support informed to disable the enable protected mode at startup and enable enhanced security. 
We have noticed that we need to disable these security options AND also Collaboration Sync from starting up in order for the systems to remain stable. A workaround, not a solution though.

We believe we fixed this issue btw. It appears that AdobeCollabSync.exe was likely causing the crashing. It would open several process on startup/login. We didn't need the .exe in our organization so we created a baseline in MS Config Manager to detect and delete the .exe from all devices. Once we did that we dropped from 60-70 PCs crashing a week down to 1-2 and it was because they hadn't run the baseline.
