[SOLVED] The agent (pma_agent_ui process) takes high CPU.

Hello,
I'm the Apple Specialist of a University, and we have a lot of Mac Computers.
Some of the Mac computers have the latest OS (10.15 Catalina), most of them have the previous OS (10.14 Mojave).
Since the version 8.0.0.94 of the Agent, the Process "Parallels Mac Management for Microsoft SCCM" takes more than 95% of CPU, no matter the version of the OS.
We ask Parallels for support and they answer this :
Following up on the (tangentially-related) issue of the CPU-hogging process that reappears when killed, the heavy-handed way to make the problem go away is
sudo chmod a-x /Library/Parallels/pma_agent.app/Contents/MacOS/pma_agent_ui
then kill the process. Parallels still works after this change, and Parallels Application Portal _appears_ to work as well, although I Have not tried to install anything with it after the change. However, since the rogue process appears to be part of the Application Portal, I would not be too sure that this would work ...
Original permissions for the executable are -rwxr-xr-x 1 root wheel 5565760 26 Sep 02:07 /Library/Parallels/pma_agent.app/Contents/MacOS/pma_agent_ui

It seems to work, but we have around 1000 Mac end-user !
So I created a package to push the command line on all the Mac computers. But when it update the agent, the problem comes back.

Yesterday, we updated SCCM to the 1906 version. I hoped that having a new agent will fix the issue.... But no.
The Agent version is now 8.1.0.14 and it still takes more than 95% of the CPU usage, which implies that the fans turn noisily.
Nothing found on google search..

Do you have similar issue ? do you find a better solution ?
thanks

 

Here the sample of the process :

Hello,
It's hard to say right now why pma agents take 95% CPU on macs. It will be better to investigate this behavior within a support request.
Please submit a ticket and attach your previous ticket number.

 

It seems it has been fixed with the new version of the agent 8.1.0.14. Thanks
