I have a -HEAD (11-CURRENT) box that has 64G of memory, but very little load. The ZFS ARC grows to eat most of it, but I see around 200M in use in SWAP. This was under control in 10.x. I'm wondering what information y'all need to help diagnose why. borg.lerctr.org /home/ler $ uname -aKU FreeBSD borg.lerctr.org 11.0-CURRENT FreeBSD 11.0-CURRENT #32 r281050: Fri Apr 3 16:41:13 CDT 2015 root@borg.lerctr.org:/usr/obj/usr/src/sys/VT-LER amd64 1100067 1100067 borg.lerctr.org /home/ler $ borg.lerctr.org /home/ler $ top last pid: 26313; load averages: 6.92, 6.79, 6.83 up 1+16:26:05 09:23:13 80 processes: 4 running, 76 sleeping CPU: 0.0% user, 46.9% nice, 0.3% system, 0.0% interrupt, 52.8% idle Mem: 281M Active, 539M Inact, 59G Wired, 18M Cache, 8128K Buf, 1241M Free ARC: 55G Total, 42G MFU, 9766M MRU, 1044K Anon, 568M Header, 3437M Other Swap: 128G Total, 205M Used, 128G Free -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 E-Mail: ler@lerctr.org US Mail: 108 Turvey Cove, Hutto, TX 78634-5688
