Hold Alt-SysRq and press TUSB in sequence. (IIRC it is B for reboot). That should leave stack traces of all running process in /var/log/messages. If it does not ... well, what do you do on Solaris when you are unable to take dump? :-) Note it is not a crash dump in the usual sense but still it can give you indication what processes were (not) doing - or where they were sleeping. There is kdb that can be used to live analyze your system, but I have never used it. -andrej
