RdrCEF high cpu usage

[jairop52591993]

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.

Likewise. 2016 RDS farm servers

Almost all our RDS servers suffer from cpu problems.

Thank you very much.

We found the exe for Reader DC 64 bits but it is not compatible with Adobe DC Pro.

Do you have both versions on your RDS servers ?

Thanks.

We do not, we only run Adobe Reader DC 64 bit. Is your Adobe DC Pro also
64 bit?

Yes, We tested Reader DC 64 bits et Pro DC 64 bits but it's not compatible.
