Just curoius if anybody has tried playing with swap over ggate? I thought I'd be clever and try to use it as a better workaround for the vinum swap problem... i.e. instead of running it through md(4) and a filesystem, do something like: ggatel create /dev/vinum/swap swapon /dev/ggate0 That seemed to attach just fine. However, doing something like dd if=/dev/zero of=/dev/null bs=256m count=2 to provoke some swapping caused the system to freeze. It was kind of weird for a minute -- I could still ping it and switch windows in screen, but the shell wouldn't respond to any commands. Eventually it stopped responding to pings altogether and the ssh connection died. Seemed like a VM deadlock, but unfortunately I was remote at the time and couldn't try to break in to DDB at the console. Funny thing was that after a reboot I did the same thing and it worked fine. If I'm able to reproduce the freeze again I'll try to get ps and backtrace and all that good stuff. Craig
