But, it happened later in the process. The journal did show Aug 25 02:27:15 localhost-live anaconda[2042]: program: stderr: Aug 25 02:27:14 localhost-live anaconda[2042]: program: Running... umount /run/install/source Aug 25 02:27:13 localhost-live earlyoom[1015]: sending SIGTERM to process 2042 uid 0 "anaconda": ba dness 77, VmRSS 55 MiB Aug 25 02:27:12 localhost-live earlyoom[1015]: low memory! at or below SIGTERM limits: mem 4.00%, swap 10.00% Aug 25 02:27:12 localhost-live earlyoom[1015]: mem avail: 44 of 1191 MiB ( 3.77%), swap free: 0 of 892 MiB ( 0.00%) So, it would seem, zram based swap is less forgiving than disk based swap. -- The key to getting good answers is to ask good questions. _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
