When =20= trying a local login i only got load: 0.09 cmd: login 1611 [zfs] 0.00u 0.00s 0% 208k I found one post like this earlier (by Xin LI), but nobody seemed to =20 have replied... in my current conf, I think my kmem/kmem_max is at 512Mb (not sure =20 though, since I've edited my file yesterday for next reboot), with 2G =20= of system RAM.. Normally I'd run kmem(max) 1G (with arcsize of 512M. =20 currently it is at default), but since I just got back to 2G total mem =20= after some hardware problems I've been runnig at those lows (1G total =20= is kindof tight with zfs..) Well, just wanted to report... The box is not totally dead yet, ie I =20 can still do Ctrl-T on console, but thats it.. I don't really know =20 what more I can do so.. I don't have KDB/DDB. I'll wait another hour or so before I hard reboot it, unless it =20 "unlocks" or if anyone have any suggestions. Thanks -- Johan Str=F6m Stromnet johan@stromnet.se http://www.stromnet.se/
