So something is stopping the admin server from being able to see observiced on the client. Check on the client /usr/tmp/observiced.log to see if there were any problems starting up. The webmin installation on Solaris will use port 10000 by default so that needs to be changed if it is started.
Yeah i checked and there is no error on that log /usr/tmp/observiced.log. When i executed a third party script to find out the apps running the port 10000.
Its showing observiced and some oracle middleware apps are using the port 10000 with different PID.
