Hi ,

I have setup of Oracle RAC 10g on RHEL4 with 2 nodes. All RAC services on setup are running fine, but I am not able to connect to oracle some times i get error in listerner.log as

TNS-12520: TNS:listener could not find available handler for requested type of server

after stopping and starting listeners on both nodes it starts working fine. can any one comment why this is happening and how resolve this.
