It is impossible to say why it happened from top output alone. sysrq-m output may provide some clue.
I know, there is not enough information.
How can I do sysrq-m over ssh? Because locally the machine did not respond at all, black screen.
Output goes into dmesg so should be captured by journald/klogd/whatever.
Keyboard does not respond. Screensaver interferes.
Also /proc/meminfo displays similar information.
That I can get. I have ssh responding slowly. Machine is locked now. One command responded after 5 minutes: minas-tirith:~ # free -h total used free shared buff/cache available Mem: 3.8G 3.3G 100M 240M 315M 20M Swap: 6.0G 1.4G 4.6G minas-tirith:~ # 'top' has not yet displayed, since 30 minutes I started it. I'm trying to scp the output of "cat /proc/meminfo" info, no response yet. But it has not timed out either. I will do "echo m >/proc/sysrq-trigger" now. I don't know where it will dump the information. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
