I was trying to start the Managed servers (10 in my case) from Weblogic console > Servers page when I hit this error approx 10 mins later.
“A timeout occured while interacting with <managed_server>. Limited information is available.”
To resolve the issue :-
a) Kill Node Manager processes in all the Managed Servers.
ps -ef | grep NodeManager and kill the respective processes.
Tried clicking Server link > It should open immediately.
b) Start Node Manager now $WL_HOME/server/bin/startNodeManager.sh
c)and Start Managed Servers from Console now.
