After several days running, this morning it locked as soon as I changed workspaces. I noticed kswapd0 was busy long time, and that firefox had about 10 gigs of virtual memory. The disk activity led was solid blue. I couldn't find out more, the machine froze and had to be hard rebooted.
Sometimes, this gets logged as OOM. Have you checked logs from the boot right before the reboot?
Yes, nothing. The word "OOM" is nowhere in the logs from 2019-01-28 to 2019-02-05. /var/log/messages during the event: <3.6> 2019-02-03 13:00:01 Telcontar dbus-daemon 1537 - - [system] Activating service name='org.opensuse.Snapper' requested by ':1.10447' (ui d=0 pid=29269 comm="/usr/lib/snapper/systemd-helper --timeline ") (using servicehelper) <3.6> 2019-02-03 13:00:01 Telcontar dbus-daemon 1537 - - [system] Successfully activated service 'org.opensuse.Snapper' <10.6> 2019-02-03 13:00:01 Telcontar cron 29258 - - pam_unix(crond:session): session opened for user cer by (uid=0) <10.6> 2019-02-03 13:00:01 Telcontar cron 29257 - - pam_unix(crond:session): session opened for user cer by (uid=0) <9.6> 2019-02-03 13:00:01 Telcontar CRON 29292 - - (cer) CMD (/home/cer/bin/dar_la_hora_en_cron hora) <10.6> 2019-02-03 13:00:01 Telcontar CRON 29257 - - pam_unix(crond:session): session closed for user cer <10.6> 2019-02-03 13:00:05 Telcontar CRON 29258 - - pam_unix(crond:session): session closed for user cer <3.6> 2019-02-03 13:06:46 Telcontar smartd 1473 - - Device: /dev/sdc [SAT], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 7 8 to 79 <3.6> 2019-02-03 13:06:46 Telcontar smartd 1473 - - Device: /dev/sdc [SAT], SMART Usage Attribute: 195 Hardware_ECC_Recovered changed from 7 8 to 79 <3.6> 2019-02-03 13:09:28 Telcontar systemd 1 - - Started Leafnode NNTP server (127.0.0.1:35362). <3.6> 2019-02-03 13:09:28 Telcontar systemd 1 - - Started Leafnode NNTP server (127.0.0.1:35360). <10.6> 2019-02-03 13:20:01 Telcontar cron 30074 - - pam_unix(crond:session): session opened for user cer by (uid=0) <10.6> 2019-02-03 13:20:01 Telcontar CRON 30074 - - pam_unix(crond:session): session closed for user cer <10.6> 2019-02-03 13:24:05 Telcontar unix2_chkpwd - - - gkr-pam: unlocked login keyring <3.6> 2019-02-03 13:24:11 Telcontar systemd 1 - - Started Leafnode NNTP server (127.0.0.1:35744). <3.6> 2019-02-03 13:24:11 Telcontar systemd 1 - - Started Leafnode NNTP server (127.0.0.1:35742). <10.3> 2019-02-03 13:28:54 Telcontar cron 30378 - - pam_systemd(crond:session): Failed to create session: Connection timed out 2019-02-03 13:34:47+01:00 - Booting the system now ================================================================================ Linux T "Started Leafnode NNTP server" is probably when I successful sent one nntp (news) post on Thunderbird on workspace 2, instants before it hanged.
