I got a system that is hung, unable to do most unix commands like ps/who etc... I did: dtrace -c /usr/bin/ps -n ''pid$target::open*:entry {printf("%s %s",execname,copyinstr(arg0)); }'' and it hangs here: 7 65277 open:entry ps /proc/19729/psinfo 7 65277 open:entry ps /proc/11687/psinfo ^C So, I tried to kill -9 11687, but that returns with nothing. If I do "ls /proc", I still see it. I am unable to cd into /proc/11687/psinfo either. Anything else I can do other than reboot? -- This message posted from opensolaris.org

[dtrace-discuss] hangs when doing open /pro/pid/psinfo
I''ve seen this when NFS servers are down. If you end up rebooting, do a reboot -d to capture a crash dump for analysis.
