Since I updated to the Feb 25 -CURRENT I'm currently running (from mid-Sept, I believe), I see similar. It seems like the ARC has gotten really unwilling to yield, so it grows up in size, and then doesn't let up under pressure. I saw programs being actively used constantly swapping their working set in and out, since they were left with tiny available memory. Hard-slappping vfs.zfs.arc_max down a ways mitigated it enough to get me through the days, but is a pretty gross hackaround... -- Matthew Fuller (MF4839) | fulle...@over-yonder.net Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream. _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
