Hi, to fs_at_, please CC me, as I'm not subscribed. I monitored (by hand) a while the sysctls kstat.zfs.misc.arcstats.size and kstat.zfs.misc.arcstats.hdr_size. Both grow way higher (at some point I've seen more than 500M) than what I have configured in vfs.zfs.arc_max (40M). After a while FS operations (e.g. pkgdb -F with about 900 packages... my specific workload is the fixup of gnome packages after the removal of the obsolete libusb port) get very slow (in my specific example I let the pkgdb run several times over night and it still is not finished). The big problem with this is, that at some point in time the machine reboots (panic, page fault, page not present, during a fork1). I have the impression (beware, I have a watchdog configured, as I don't know if a triggered WD would cause the same panic, the following is just a guess) that I run out of memory of some kind (I have 1G RAM, i386, max kmem size 700M). I restarted pkgdb several times after a reboot, and it continues to process the libusb removal, but hey, this is anoying. Does someone see something similar to what I describe (mainly the growth of the arc cache way beyond what is configured)? Anyone with some ideas what to try?
