ok.So after downgrading libc and openjdk-11 didn't help. I've downgraded my eclipse installation from 2020-3 to 2019-12.
And since then it was running stable, for several hours.Is it possible, that that is a strange bug in eclipse, or would it just be, that the new version of eclipse triggers an until yet undiscovered bug in openjdk-11?
Maybe somebody who knows more about this stuff could answer me?
