The number of connections that can be supported in a NETSRV address space is limited by the amount of available extended private storage. Once the limit has been reached, the server socket is closed and any attempt to start a new connection from the local JES will fail with this message.
The attempt to start a new connection is failed.
If additional NETSERV address spaces exist, send the request to start a new connection to a different NETSERV address space,
Notify the system programmer if additional NETSERVs need to be defined, or locally originated connections need to be better balanced between existing NETSERV address spaces.
Consider adding an additional NETSERV address space to increase the capacity to support NJE connections. Or if additional NETSERV address spaces already exist, the locally originated connections may need to be balanced between he existing NETSERV address spaces. For more information, see the appropriate JES initialization manual ( z/OS JES2 Initialization and Tuning Reference or z/OS JES3 Initialization and Tuning Reference).
