EZD1362A
NSS SERVER IS WAITING FOR TCP PORT portnumber

Explanation

The network security services (NSS) server has been configured to listen on TCP the specified port but it cannot bind to that port because another process is currently using it or because the port is not configured for access.

In the message text:
portnumber
The TCP port number to which the NSS server is trying to bind.

System action

The NSS server continues to wait for its port to become available. This message will remain on the console until one of the following occurs:
  • The port is released and the NSS server is able to bind to it. Processing continues normally from this point.
  • An unrecoverable error occurred while attempting to bind to the port. The NSS server ends.
  • The operator clears the message from the console manually. The NSS server continues to wait for its port. Processing continues when either the port is obtained or the NSS server ends.

Operator response

Contact the system programmer.

System programmer response

Verify that the NSS server is configured to use the correct TCP port. If the NSS server is configured correctly, then determine which other process is using the TCP port or whether there is a configuration error for the TCP port itself. See z/OS Communications Server: IP Configuration Guide for information about configuring the NSS server and z/OS® TCP ports.
