https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276402 Bug ID: 276402 Summary: tmpfs: memory reserve does not account for ARC Product: Base System Version: 15.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: throwaway_vthgwq4@protonmail.com When there is tmpfs entry in fstab without size specified, e.g. none /var/run/user tmpfs rw And ZFS ARC fills available memory fully, writes to tmpfs will fail with no space left on device, ARC won't be reclaimed. This results in hangs when switching browser tabs or spawning Wayland clients in e.g. x11-wm/sway which uses XDG_RUNTIME_DIR on tmpfs. Disabling memory reserve with sysctl vfs.tmpfs.memory_percent=3D100 restores old behavior (ARC is reclaimed for tmpfs) and gets rid of hangs in x11-wm/sway. --=20 You are receiving this mail because: You are the assignee for the bug.=
