Whenever you modify the configuration parameters in Primary server,those
changes needs to apply manually in standby server.

If you do not perform changes in standby server,Standby server will
shutdown automatically with above error message.

Please change "max_connection" parameter in postgresql.conf file of standby
server according primary server and then start the Standby server.
