IAZ0550I server_name NJETCP Server socket closed because socket limit of nnn reached
Explanation
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, preventing any new connections from being established to this NETSRV.
If there are other NETSRV address spaces that are listening to the same IP addresses and port, new connections will be directed to those other address paces by TCP/IP. Otherwise, connections will fail.
- server_name
- The NJETCP server name.
- nnn
- The address space calculated connection limit.
System action
The server socket is closed. Once the number of connections drops below the displayed limit, the server socket is opened again and new connections can be established.
Operator response
This can be normal operation for your installation. The connections in use can be displayed using JES or TCP/IP commands.
System programmer response
Consider adding an additional NETSERV address space to increase the capacity to support NJE connections. Additional NETSERVs can share the same port and IP address. For more information on port sharing, see the appropriate JES initialization manual ( z/OS JES2 Initialization and Tuning Reference or z/OS JES3 Initialization and Tuning Reference), and the z/OS Communications Server: IP Configuration Reference.
