Hello everyone,
are there any known memory problems (leaks etc.) with 2020.2? Right now i've set the heapspace to 8Gb but intellij is still having low memory problems. (i cant even create a memory snapshot to find the problem)

I am actually seeing something similar — combined with what looks to be like aggressive GC and general performance issues

Jepp, looking at the ideal.log i only get this in some kind of endless loop:

Interesting fact: If i close all files from the project it stays at ~480M

@Francis Altomare Do you also have problems with freezinng while typing / using copy-paste?

Oh, I too have problems with copy-paste, lots of freezing. Are you using sealed classes? IntelliJ is really struggling with my sealed classes.

[zeugederunity]

No, i found the error in a file with a ton of type parameters

[zeugederunity]

@v79 i never had problems with sealed classes. but i never used them excessivly. Like my biggest "sealed tree" has like 7 leaves.
