https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=277389 --- Comment #20 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Mark Millard from comment #19) I updated to a PkgBase vintage of: # uname -apKU FreeBSD 7950X3D-ZFS 15.0-CURRENT FreeBSD 15.0-CURRENT main-n268827-75464941dc17 GENERIC-NODEBUG amd64 amd64 1500015 1500015 and added to /boot/loader.conf : nullfs_load="YES" vfs.nullfs.cache_vnodes=0 I reran the test for such a boot context and the vmstat -z had a notable difference for VNODE, but the Wired value stayed huge. No hangup or OOM activity happened. I'll remind that my prior report had (after the rm): VNODE: 448, 0, 1756979, 325855,17353842, 0, 0, 0 but this test got: VNODE: 448, 0, 836, 1846, 43727, 0, 0, 0 Yet: 183850Mi Wired still. [Note added later, well after the below vmstat -z output: it has slowly dropped to 151961Mi Wired and continues to decrease. I'll do another vmstat -z later.] For reference (183850Mi time frame): # rm iozone.DUMMY.* # vmstat -z ITEM SIZE LIMIT USED FREE REQ FAIL SLEEP XDOM kstack_cache: 16384, 0, 1865, 4, 1933, 0, 0, 0
