Hi All, I'm seeing the following leak in 8.2/8.3 since I re-enabled zfs on my system. compare the arc graph http://web.internationalconspiracy.org/munin/internationalconspiracy.org/potjie.internationalconspiracy.org/zfsarc_l1.html with the kmem graph http://web.internationalconspiracy.org/munin/internationalconspiracy.org/potjie.internationalconspiracy.org/kmem.html a straight trajectory of base kmem growth. non-kmem vmem usage is getting squeezed into swap: CPU: % user, % nice, % system, % interrupt, % idle Mem: 976M Active, 543M Inact, 5963M Wired, 414M Cache, 778M Buf, 1372K Free Swap: 16G Total, 2083M Used, 14G Free, 12% Inuse I've dumped everything I can think of here if anyone wants to take a look: http://trull.org/~alex/src/Debuggery/20120703-leakykmem/ Regards, Alex
