IntelliJ IDEA 2019.2.4 Ultimate is running a lot of process

Where do you see these processes? The https://youtrack.jetbrains.com/issue/IDEA-223667 may be related. Please try 2019.3 from https://www.jetbrains.com/idea/nextversion/

I see the message within IntelliJ, in the bottom of the IDE. Regarding the issue IDEA-223667, how can I verify that I'm suffering the same issue?

Unfortunately, I can't use EAP versions for my job, I'd rather to use the ultimate license that my company provides us.

Thank you very much for your prompt response.

Please show what do you see exactly, what messages.

EAP does not require a license - you can install it temporarily and run at the same time with 2019.2 version.

Find attached a screenshot with the message "X process running"

If I click in this message, a "Background Tasks" screen appears:

And here it is an extract of the idea.log

It's getting worse as time passes:

601 processes running...!

Do you use any 3rd plugins? Try disabling if you do.

If problem remains it would be great if you try 2019.3 version as there were a lot of changes and this issue could be fixed.

If problem remains please file an issue at https://youtrack.jetbrains.com/issues/IDEA with IDE logs zipped. It would be also useful to have several jstack thread dumps of IDE process.

Thanks for the response, and for the tip for finding the solution.

The last plugin I installed is "Save Actions" (https://plugins.jetbrains.com/plugin/7642-save-actions/) it's a great plugin that I usually use to automatically format code, optimize imports and so on.

But I'm afraid I misconfigure it and MAYBE it's continuously changing the files and therefore, IntelliJ is trying to re-compile over and over and over.

After disabling the plugin, the IDE seems to work correctly.

I will double-check the plugin configuration in order to find out what is creating the issue.

But the problem is apparently solved, so you can close the ticket.

Thank you very much and best regards.
