Hanging here is something addressed by the "UMA limit" part of head -r327485 . Bugzilla 224330 has material about it. As I understand -r326347 is what broke that specific aspect of things. (It had other issues as well, and apparently causes some other problem to show up that was previous hidden.) As for -r327485: Author: jeff Date: Tue Jan 2 04:35:56 2018 New Revision: 327485 URL:=20 https://svnweb.freebsd.org/changeset/base/327485 Log: Fix arc after r326347 broke various memory limit queries. Use UMA features rather than kmem arena size to determine available memory. Initialize the UMA limit to LONG_MAX to avoid spurious wakeups on boot bef= ore the real limit is set. PR: 224330 (partial), 224080 Reviewed by: markj, avg Sponsored by: Netflix / Dell EMC Isilon Differential Revision:=20 https://reviews.freebsd.org/D13494 . . . The "arc" reference is a ZFS file system handling issue. --=20 You are receiving this mail because: You are the assignee for the bug.=
