Seems like you are hitting a null pointer dereference in the orb invocation code path
I would recommend you do a "scconf -cq reset" as Zoram mentioned. i.e. 1. Boot up the 2 nodes that do not give a problem 2. Run the command "scconf -cq reset" 3. The boot up the 3rd node that is giving a problem. See if the node joins without panicking. If it does, then please send the stack trace ( $C ) output and $<msgbuf output -- This message posted from opensolaris.org
