https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231457 Shane <FreeBSD@ShaneWare.Biz> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |FreeBSD@ShaneWare.Biz --- Comment #4 from Shane <FreeBSD@ShaneWare.Biz> --- Actually, you don't have to use all your swap to get out of swap errors, they also happen when too much ram is wired, this prevents any ram being swapped in/out. I started getting out of swap errors on 10.1 with 8G ram. Look at "vm.stats.vm.v_wire_count * hw.page_size" at the time of getting out of swap errors, this is the wired amount shown in top. As I mentioned in bug #229764 max_wired is 30% so arc should be less than 70% ram. Another thing that often wires ram is bhyve, so any guest ram should also be considered when setting arc_max. -- You are receiving this mail because: You are the assignee for the bug.help
