So vfs.zfs.arc.min looks to be both a load-time tunable (-T) and a later writeable variable (-W). To illustrate what happens for -T and -W output when the name is loader-tunable but not later a writable variable (as an example): # sysctl -W kern.maxproc # sysctl -T kern.maxproc kern.maxproc: 70308 I'll note that I also see the 0 value for vfs.zfs.arc.min but I do no tuning of ZFS (I use defaults) and the system used for the above commands has 64 GiByte of RAM. My usage context is very different from chrome/gimp/plasmashell/Xorg and so my lack of seeing OOM activity does not mean much for the bugzilla report. --=20 You are receiving this mail because: You are the assignee for the bug.=
