https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=229670 --- Comment #8 from Josh Paetzel <jpaetzel@FreeBSD.org> --- <jpaetzel> Is there any case where ARC usage can exceed arc_max legitimately? <mahrens> I want to say no, but your example is with arc_max=128MB so there may be some exceptions at that small of a size (only 8 maximum-size blocks!). Also stuff can get pinned in memory (and can’t be evicted regardless of ARC settings) when it’s “in use”, which is the case for metadata of open files, mounted filesystems, etc. It’s a hard limit on the *target* ARC size. -- You are receiving this mail because: You are the assignee for the bug.
