Not enough is accounted for. Are there a ton of small processes created by something? Like many dozens of firefox tabs?

It's consistent. Only ~240 MB of 900M for PK had been evicted to swap. When restarting PK, it dropped those 240MB in swap. Free memory also went up no doubt. I don't know why it's using so much memory, what all these anonymous pages are. If you catch it going above 500M, check /proc/pid/status and let's see what the breakdown is of memory usage. I want to see if we can stop these SIGTERMs from happening. I suggest bumping your zram size cap to 8G. Create this file /etc/systemd/zram-generator.conf Containing just two lines: [zram0] max-zram-size = 8192 Either reboot, or maybe logout or quit a bunch of things first because otherwise with a full swap, this command is risky: systemctl restart swap-create@zram0 For that to work, it must swapoff which means all anonymous pages still in swap must be restored to memory first, before the new sized zram swap device is created and started. This doesn't solve the problem of whatever is creating so many anonymous pages. But I wonder if it levels off at something like 6G or if it just keep spirally out of control, and what's doing it. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-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/devel@xxxxxxxxxxxxxxxxxxxxxxx
