Hmm, so the set of ps output you have from DDB shows a lot of runnable processes and swi6 (Giant taskq) as the only running thread (all consistent with your hang). (And that is from your Ctrl-Alt-Esc) Do you only have one CPU in this VM? If not, do you know which threads the other CPUs were running (e.g. do you have ps7.png, etc.)? -- John Baldwin _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
