This is a follow up post of an old [post](https://intellij-support.jetbrains.com/hc/en-us/community/posts/206382229-Intellij-Idea-randomly-stops-working) of me. I gave up at that time, but I want intellij now more than ever.
The problem is, that intellij completely hangs my system on startup. Sometimes it is during the startup process, sometimes it is when it is already loaded, and showing the "tip" window. It is only when it loads a project, the "start" screen (when no project is loaded) is fine.
When I say "completly hangs my system" it means, that I cannot start any other processes. The Window manager is still responsive, and most programs are too, also I cannot open a new tab in chromium.
This is my system:
Now, it was suggested to use jsstack or strace to find the problem and post the output in the moment intellij blocks. The problem is, when I use jsstack or strace, the problem does not occure! Intellij works fine in these cases. I can even "unblock" intellij by doing
sudo jstack -F <intellij-pid>
But of course, always having jstack/strace run is not an option because of performance.
But it sounds to me, that this is some kind of dead-lock situation.
I looked into /var/log/syslog when the system hangs, and this is the last output: https://gist.github.com/RudolfVonKrugstein/90bbb5f8857c899e3805
