https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229670 --- Comment #8 from Josh Paetzel <jpaetzel@FreeBSD.org> --- <jpaetzel> Is there any case where ARC usage can exceed arc_max legitimatel= y? <mahrens> I want to say no, but your example is with arc_max=3D128MB so the= re may be some exceptions at that small of a size (only 8 maximum-size blocks!). = Also stuff can get pinned in memory (and can=E2=80=99t be evicted regardless of = ARC settings) when it=E2=80=99s =E2=80=9Cin use=E2=80=9D, which is the case for= metadata of open files, mounted filesystems, etc. It=E2=80=99s a hard limit on the *target* ARC size. --=20 You are receiving this mail because: You are the assignee for the bug.=
