The system is question is running ZFS at full steam, and the ARC might be to blame as nearly all physical memory is placed in the Wired category: Mem: 97M Active, 188M Inact, 7175M Wired, 193M Cache, 400K Buf, 249M Free This system has: real memory = 8589934592 (8192 MB) avail memory = 8234950656 (7853 MB) The solution might be to decrease vfs.zfs.arc_max from 7216345088 to a more sane number like 4096M. > GnuPG and other software would benefit from a useable mlock(2) on > the amd64 arch. -- +-------------------------------+------------------------------------+ | Vennlig hilsen, | Best regards, | | Trond Endrestøl, | Trond Endrestøl, | | IT-ansvarlig, | System administrator, | | Fagskolen Innlandet, | Gjøvik Technical College, Norway, | | tlf. dir. 61 14 54 39, | Office.....: +47 61 14 54 39, | | tlf. mob. 952 62 567, | Cellular...: +47 952 62 567, | | sentralbord 61 14 54 00. | Switchboard: +47 61 14 54 00. | +-------------------------------+------------------------------------+ --2055831798-834928694-1329382058=:7134 Content-Type: TEXT/PLAIN; CHARSET=us-ascii Content-ID: Content-Description: Content-Disposition: INLINE _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" --2055831798-834928694-1329382058=:7134--
