Hi,
Sometimes since I upgraded my laptop to 15.0, and after it has been sitting alone doing nothing for hours in the sitting room, I get to it and it doesn't respond. Right now I tried to connect to it via ssh and it is responding very slow - yast failed to start, for instance.
I see this in top, sorted by %CPU:

Why is "kswapd0" using 25% of the CPU?
The disk is SSD, I have often way more swap in use and the machine is very responsive. Not now.
Sorting by memory (RES), I do not see unexpected memory hungry processes, and they have been there for hours:

I went to it locally, touched a key, I see the backlight power up but I don't get the prompt to the password to kill the screensaver.
Response on the command line via ssh is very, very slow. I'm trying to see the log now.

The activity at 21:39 with NFS is related to me starting "yast2 single", my scripts imports an NFS share. It is then that I found the machine non responding.
I'm trying to login into another ssh as root or user, but I get kicked out after minutes of waiting.
"/usr/sbin/iotop -o -d 3.3333" shows: (takes minutes to start)
Doesn't start, and ctrl-c hangs. I have no terminal left to see that is going on.
I'll leave the machine running as is, waiting for ideas, what to check or do - if I get the prompt back.
