RdrCEF high cpu usage

Good Morning.
First of all, sorry for my low level of English.

A few days ago I installed Adobe Reader DC on all servers in my farm Citrix XenDesktop 7.6. Everything started well but now I have problems with high CPU usage. I have seen that for each user using Reader DC open between 1 and 3 processes with the same name, RdrCEF.exe. This process consumes a lot of memory and sometimes, depending on the PDF file, use much of the CPU causing performance problems in other user sessions on the server .

What is this process RdrCEF? Why it is opened several times per user ? And most importantly, how I can prevent this process use as much CPU?

I hope someone can help me.
Thank you.

Since we could find no other solutions, we removed Adobe Reader DC and installed Foxit Reader. We have no problems with CPU usage now.


Reader DC 2021.00.7.20091 32bit version was causing trouble for us on our 2016 RDS farm srevers. I tried running updates, repairs and reinstalling but no luck. Upgrading to the 64bit version has seemed to do the trick for us.

What about the same trouble with Apple OS El Capitan 10.11.6 + Adobe Acrobate Reader DC 2015.017.20053 ?

Same thing here. Out of nothing, suddenly, when opening a PDF file, my mouse pointer changes and adds the blue circle (indicating on Win10 that some program is busy). When I check with the taks manager, it is indeed RdrCEF.exe which is causing this insane load. It simply doesn't go away, even if you leave it to it. Restarted Adobe Reader, restarted my pc, ... all the same.

Shame on you, Adobe that you leave this problem for almost a year now! (Although apparently, it seems not to affect all people all the time. It is just since yesterday that I noticed the problem for instance.)

Oh, my version: 2015.017.20053

Hi David and those who face the same problem.

Fully agree that Adobe shouldn't leave the problem without solution.

Apparently it's a compatibility issue between RdrCEF.exe and windows versions after Vista.


For David and anyone else who has the same configuration (Win10, Adobe version: 2015.017.20053) a simple and quick solution:
1. Go to: C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroCEF
2. Right Click on "RdrCEF.exe"
3. Select Compatibility tab
4. Either run compatibility troubleshooter and try the different versions or tick compatibility mode and select "Windows XP (Service Pack3)"
5. The issue will stop without losing functionality
Another solution is to roll back to Adobe reader 11.
Hope it helps.

Hi All,

Would you please try the following:

- Restart the machine, and confirm if you're still seeing the crash problem?

- If yes, can you enable Windows WER crash reporting feature on one of the machines in which the problem occurs and share the crash dump file via. some file sharing service with us.  You may use Google drive or Adobe Send https://cloud.acrobat.com/send

Steps to enable crash dump creation: Collecting User-Mode Dumps (Windows)

If you need any help in creating dumps, please let us know.

Regards,

Tariq Dar.

I would also like to know if there was an update to this?  I am in charge of keeping reader up to date in our multiple Citrix environments and I am seeing this process consume resources just on my local machine.  I do not want our user capacity to go down due to Reader.

Hi jairop52591993,

We are looking into the high CPU usage issue you are facing on citrix. Can you please provide some more information:

On Citrix, there are multiple users and Reader launches a new RdrCEF process for each user. Do you see high memory being consumed on the server side? Could you please send us more details of the issue you are experiencing. A screenshot depicting the high memory usage would also be helpful.

Thanks,

-Amboo

Hi aadeshs76610910‌,

I have Adobe Reader DC version 2015.009.20079.

I have a citrix farm where each server typically runs 15-20 user sessions.In the task manager of each server there are two or three processes RdrCEF.exe for each user session.


Thanks for the reply.

Jairo.
