I also have this issue with mac running Ventura. Memory usage causes a crash on a simple word document. Deselecting page cache makes no differnce.

Adobe ist **** and doesnt care, use cracked Adobe Acrobat, its wonderful and stable.

I am exascerbated with this same issue. I literally can't scroll through documents period. Stalls, crashes, open file again, repeat. These are 70 MB files, they are not enormous. Is there a way to open a low resolution version or save out as an image instead of all the pdf layers? I tried TIF and it only will save one page at a time, separately. I have already resorted to printing a 300 page document with similar content. This is 60 pages. Would an alternative software an option. I flat out can't do my work. I have a nice computer with 16GB of RAM. Windows.

I've had this problem ever since Acrobat auto updated too long ago! I'm sure a fix was promised by Adobe in a future update but has never happened. I can't believe they have the front to take subscriptions for Creative Suite and do nothing to fix this problem. It don't think it is an Enfocus issue as I've been on Pitstop 13 for over four years and Acrobat is the only thing that has changed. The lack of response from Adobe is a disgrace, they are as complacent now as Quark were when they enjoyed a position of dominance.

At one point an Adobe tech recommended that I add more ram. I was operating with 8GBs and the suite requires a minimum of 16 I believe. I maxed out my ram and haven't encountered an issue since, nor does Acrobat grab all available empty ram anymore

Im having the same problem, so bad that I have to wait until it allows me to write the next letter on almost every word. How do we get rid of this? I am on an iMac with an intel core i5 and runing Mc OS High sierra

Hi Folks

I have fixed my excessive RAM problem with Acrobat DC on my mac running High Sierra, and hoping I can help others out with my find.
Here is how I did it:

Quit Acrobat DC

Go to HD/Users/user/Library/Preferences

you will see an "Adobe" Folder
In there you will see a folder called "DC" - move the whole folder out and put it somewhere else on your mac.

Now find these files in the preferences folder and move them out too:

com.adobe.Acrobat.Pro.plist

Acrobat Distiller Prefs

Acrobat WebCapture Prefs

com.adobe.Acrobat.Pro.plist.IATI4SF

I just created a folder on my desktop called Acrobat DC Preferences and moved everything into that.

Now open Creative Cloud, click on Apps tab, and look for Acrobat DC
Where it says “Open” click on the arrow next to it and select “Manage” then uninstall.

It will ask for your admin password and also ask if you would like to uninstall any older versions.

You have to say yes to uninstall older versions, or it won’t complete the uninstall.

Once this is done, look for Acrobat DC in the list again and click the update button.

Acrobat DC will now install again.

Once that has completed, install your Pitstop if applicable.

I have been using Acrobat DC now for a few days, with no issues.
I’ve kept Activity Monitor open to keep and eye out.
I’ve noticed if i open a big file, the memory increases and when in close the file it drops back down again.

No more 45gb of RAM being used if i have it open for an hour.
I’ve had it open all day now, checking files, pit stopping files, organising pages and the MEMORY in Activity Monitor, is staying consistent.

Hope this is useful for other people out there having problems with this issue.

I've recently updated my 2012 iMac to High Sierra, so I can run CC 2019 and my Acrobat DC was making my system run out of memory and everything running slow and constant spinning balls.
The only way round it i have found it to uninstall DC and install X1. Luckily Pitstop 18 works fine on X1. Since i have been running X1 with DC uninstalled, my mac hasn't slowed down once and no spinning balls whatsoever. How can this have been going on for over a year and still under review?
It's not good that you have to downgrade your application, that you are paying a huge subscription for, just so you can do your job at a normal pace rather than a snails pace, due to buggy software.
Come on Adobe, sort it out!!!

Why!!!!!!!!!!!..... at least I know those of you who are following this thread are feeling my pain as well.

It's so tedious, day in day out and the combined minds of Adobe can't sort out a seemingly simple problem of memory drain.

Oh well, another force quit and start over, so tedious.

So far after a week with the new user login, I havent had to quit acrobat. It has had its usual share of crashes but not due to the memory issues.
I think creating a new user has definately helped me.
And I accidentally logged into the old user, with the updated software on monday and acrobat crashed again about half an hour later, so the update didnt do a thing

If anything this latest update seems to made the issue worse on my mac! I've resorted to quitting Acrobat much more often as it has a vicious habit of eating up much more memory when I'm not looking!!!

I read Jan's comment yesterday and eagerly updated to 2019.008.200.74, my high hopes were dashed this morning when I had to force quit acrobat as it was using 162Gb of virtual memory. So no change and back to square one.

Finally! the memory problem on 2 of our Mac systems are gone. I've installed the 2 latest updates for Acrobat Pro. I'm running on version 2019.008.200.71.
I've waited a whole year for this!

So I have finally been able to create a new user and get everything working as per my old user (mail, all my software, logins etc), and so far ***touch wood*** after two days I have yet to have a crash in acrobat.
I am hopeful, but I have had others try this and still had the same issue eventually start up again... I really dont want to be doing this every few months.

Final post to 2nd support case. Nevermore to deal with Adobe about this problem.

"Why I come here and update this case when it's become blatantly obvious that no one at Adobe is paying any attention to this is beyond me!
Tech failed to call as scheduled time on scheduled day, he called the day after. THEN, he wanted to remote in and collect logs. Presumably the SAME LOGS I HAD COLLECTED WITH YOUR LogCollectorTool, which the app said it uploaded. BUT, the tech said, "Sorry, we never received them".
WTH ADOBE! DO I NEED IT MADE ANYMORE CLEAR TO ME THAT YOU DON'T CARE ABOUT THIS PROBLEM OR HOW IT AFFECTS THE WORKERS AND BUSINESSES THAT PAY MONTHLY TO USE YOUR SOFTWARE??? Forget it all, close the case. I have my workarounds and as long as they work I won't waste anymore of your time trying to help you fix what's broken!

Nearly two weeks later, daily bot emails threatening to close my case. Here's my latest/last chat on the subject:

Minakshi Mishra: Hello. Welcome to Adobe Technical Support.
Minakshi Mishra: How are you doing today?
Harold Anderson: could be better
Minakshi Mishra: Harold, I really apologize for the inconvenience caused to you. I assure you that I will try my best and get this issue resolved as soon as possible.
Minakshi Mishra: As per mu understanding you want to close the case, am I correct?
Harold Anderson: no, you guys have closed the case without acknowledging anything about the problem. I originally asked for Acrobat developers to review this thread on your bug report pages: https://acrobat.uservoice.com/forums/590923-acrobat-for-windows-and-mac/suggestions/31664974-acrobat-cc-excessive-ram-usage?tracking_code=aabc37a804b90303e7b72a84cb7cfa73
Minakshi Mishra: Could you please share the screenshot with me of the error your are facing?
Harold Anderson: Many people are having problems with Acrobat DC gobbling up all ram and VM and bringing both Mac and Windows systems to a crawl. Over the past week I've received NOTHING but "waiting for your input" emails, gone to the support case and given input, THEN I get a call saying you're going to close it and now I've received an email notifying me the case is closed. Fine, Adobe has been ignoring the thread for over a year and a prior chat has resulted in ABSOLUTELY NO feedback from Adobe as to acknowledgement of the problem. I'll share a log I have showing what I think is the culprit, gobbling up the ram but I'm done! I have my workaround (to quit acrobat whenever not in use) and I've wasted enough time ******* my head against the Adobe corporate wall!
Harold Anderson: Here's the log, I've got to go. have a good night or day or whatever part of the world you're in.

Anonymous, I really don't think it's a Pitstop issue, maybe something internally with Acrobat and it incorporating plugins, but not directly Pitstop. The problem for me manifested out of the blue, with no upgrade to Acrobat Pro DC, or the FusionPro plugin (only one installed at the time). I had been running fine for quite some time (year or more) with only the FusionPro plugin and no problems.

I am leaning more toward what I found in the portion of a log I posted below. It's a log detailing an Acrobat crash, force quit, after bogging my system down by grabbing memory. I'm certainly no programmer but the log clearly shows Acrobat's "malloc" operation allocating 34.1 GBs of memory. This from the wiki page concerning Malloc has me even more convinced:
"Manual memory management is known to enable several major classes of bugs into a program when used incorrectly, notably violations of memory safety or memory leaks. These are a significant source of security bugs."
https://en.wikipedia.org/wiki/Manual_memory_management

I also believe this post may be related to the following reports:

Believing this may be an Enfocus Pitstop issue, I've reached out to their support to see if they can replicate the fault on their machines. That said, they were unable to do so, but so that the Adobe Technicians can rule out Enfocus as an issue, the Enfocus support ID reference was ENF-00126172 and I was speaking to Jan De Brabanter at Enfocus Support.

After speaking to Adobe support, I am going to try logging in to the computer using a different log in... of course that means setting up a completely new user with all the access to software i currently need... bit of a major effort.
So far it seems to be working but I have yet to set up the user as i need it to be for me to use, i.e email etc, so once i have done that and run for a few days, I will report back.
Someone else through work suggested it may be something in the current users library (i.e. something conflicting with acrobat that is causing the issue/conflict), so setting up a new user could fix it.

will see if it works ;-)

Not sure why Adobe support hasn't come back to suggest this if this does fix the issue??
