In response to Ric's comment of 11 April - I am still experiencing the same issue with a new mac and the latest Mac OS update. It seems quite clear that the problem is with the software and not the operating system. More memory is available, so the programme uses more memory during memory spikes. If I don't catch it this then forces other open softwares to pause or close.

Is anyone still having this issue after the latest Mac OS update 10.13.4. I updated a few days ago and haven't yet had to restart Acrobat!! I hope I'm not tempting fate!!

The last reaction from Adobe on this thread has been posted on Nov 6, 2017. Are you still with us Adobe?
Several months month ago I did a chat with an Adobe employee to solve the problem. But without succes.

In addition to my earlier reactions:
Last week I received a message from another colleague from our Prepress department that her system suddenly had the same memory problem as my other colleague!
A few weeks ago she received a brand new iMac. I’ve copied her old workspace to the new workstation with the Migration Assistent. The source was the Time Machine backup I've made that day. After this action all of the software worked perfectly for a couple of weeks.
The strangest thing: She had installed Enfocus Pitstop Pro 13 some years ago on her old system. Acrobat worked fine in combination with this plugin.
But after 2 weeks after this migration Acrobat shows the memory leak on the new system.

I have really no idea what causes this problem and how to solve this. For the moment I have advised my colleague to close Acrobat every time when she has finished a job. There are a lot of jobs during a day.

My questions:
1) is it still a coincidence that another system with Acrobat and Pitstop Pro installed shows the memory leak?

2) Is it possible to reset the preferences or cache of Acrobat? Maybe that solves the problem.

3) How can I install a earlier version of Acrobat (2015 or XI) as a temporary workaround while waiting on a solution to this problem? On the internet I read that a lot of people use this workaround with succes.The Adobe Desktop App doesn’t provide that option. Why not? Me and my colleagues work with the most expensive Adobe prescriptions and I see it as a service that Adobe in this case provides an older Installer of Acrobat.

Please help!

1 hour, 40 minutes with support, remote access, Acrobat wouldn't show the issue, logs collected and passed to rep.....

50 minutes and FINALLY a rep has come to chat.

You have voiced my experience exactly, likewise I'm very short of time and started down the route of calling customer support and handing my system over to them to diagnose. The problem reoccured immediately after the support session, and I contacted them to tell them so - but I just didn't have the time to keep giving them access to my system. This seems to be an increasingly common problem that they don't seem interested in rectifying

I agree Chris, that I'd like to discuss "face to face" this problem with Adobe but chat/phone support isn't an option as I have no time to sit on hold or waiting for representative to get on chat. Trying chat now, been 15 min. and all I get is "Thanks for your patience. Representatives are currently helping other customers and we will be with you shortly.". Will keep the page loaded, checking as I can as I work files. Fact is, it's a problem with their software, perhaps exemplifying a bug with OS X, all we're left to do is deal with the workarounds because they aren't in any rush to fix it, let alone even acknowledge that the problem exists. Adobe is too big with their fingers in too many pies to have to care.

If I might suggest, call Adobe and get their technical support involved - and then let us all know how you got on. Sadly posting on here doesn't seem to be getting their attention

I am using Acrobat DC. This was installed on a late 2012 iMac using El Capitan. I have upgraded to a brand new mac with more memory and a faster processor, but am alarmed to see that the memory usage spikes continue - only when Acrobat DC is open. This is definitely a problem with the software and it appears that there has been no helpful resolution since 2016. I have completely uninstalled and reinstalled Acrobat DC, uninstalled and reinstalled Pitstop plug in and even recently reloaded the operating system (which caused other issues). Nothing has resolved the memory usage issue - which pauses other softwares open at the same time, often requiring a force quit. Any suggestions much appreciated.

I have been using Acrobat XI for the past few months, I tried Acrobat DC again - it seemed ok, then memory problems started again. Everyone on this forum must pay for, or the company they work for must pay for the Adobe subscription.

As before I am asking –why has this not been patched yet?

I’ve been repeatedly frustrated by poor technical support and apparent Adobe indifference to sincere requests for help.

Adobe’s technical support system is defective.

Technicians give stock answers, fail to listen, and may be discouraged from brimging problems to management.

And management either wants deniability or doesn’t care.

Only by getting the attention of top Adobe management through PC Magazine or internationally independent forums will Adobe possibly turn to and respond to its ******* customers.

yet again i am asking for a response from adobe!!
Its been 6 months now, I have restarted acrobat at least 15 times today after only 5 hours, plus a couple of restarts when the Ram has overloaded and forced me to restart.... this is driving me insane!
Not to mention slowing production down. Does adobe actually want to fix this issue?

This is complete BS! If my boss were to pursue legal action he could easily claim at least 1/4 of last years salary in lost wages waiting for Adobe apps to launch, dealing with their bugs and resetting preferences because of corrupt preferences.
I will take Chris' advice and try (as time and patience will allow) to contact by phone and/or chat. Been waiting for representative in chat for about 25 min. now.....

Those dependent upon this software for their livelihood have been harmed by the ongoing Adobe Acrobat Pro DC defective misuse of RAM memory.

Adobe has been derelict in failing to resolve this harmful defect over the several months since it has been brought to Adobe’s attention.

Acrobat customers might consider legal action to compel Adobe to address and fix this harmful software defect.

Problem is NOT resolved.

The expensive Adobe Acrobat Pro DC software has become extraordinarily disfunctional. It uses up 16GB RAM quickly and declares out of memory. It is sluggish. Adobe has known about this major defect for several months now.
Why no bug fix?

If you haven't already, get customer support involved, I contacted Adobe tech support yesterday and they spent a while looking at my system. Unfortunately I had to cut it short without any resolution as it reoccured shortly after, but I did point the service tech at this message board and the more of you that do the same will only help and lend weight to our voices. Start bugging them and we might get somewhere.

Thanks for that Harold. Adobe has responded here but not for several months now, might have to post on the other thread as well!

This is also being addressed in this thread and Adobe has responded.

and following up again... 6 months since it first appeared ADOBE, c'mon let us know if you are taking this seriously or just brushing it under the rug?

Still struggling with Acrobat DC and it gobbling up memory. Could pollute this thread with Activity monitor shots showing it holding upwards of 60 GBs of VM or maybe paste long Console logs that mean nothing to me, but why if Adobe is just ignoring the problem? BTW, only running FusionPro plugin, no recent updates to Acrobat or that, just started out of the blue.
