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.
Carlos,
I had something similar happen 2 days ago on my Leap 15 install. It had been up a couple of days and I went back into the desktop where I had an open xterm and no commands would work at all. It was like the PATH had disappeared.
From memory it was like:
$ ssh nirvana /bin/ssh unknown command
No, this is different.
The "kswapd0" kernel process was stuck at 25% CPU, so something was trashing like hell, in a loop. Thus starting any process took minutes. I was lucky to even be able to ssh in and finally kill firefox.
As a work around, maybe use that trick with a cgroup, it was discussed here a while back.
Ok, but doing what with it? I did not see any value that was that abnormal. I mean, not with firefox. I can not touch kswapd0, that's kernel.
I think exactly the same thing as was discussed, make sure there is always memory left for the GUI to be responsive.
I'm normally running my machines with much less memory and more swap than that. This instant:
KiB Mem: 8174456 total, 6002948 used, 2171508 free, 81904 buffers KiB Swap: 25165820 total, 5668656 used, 19497164 free. 2059292 cached Mem
And there is no issue. What happened on that laptop was something else. Notice that CLI over ssh was not responsive. Nothing was responsive, I can not give more resources to the GUI to solve it. Rather, it would be limiting some resource to FF, but which? -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
