The following error might occur in the SAS^® Stored Process Server log file:

ERROR: Bridge protocol engine socket access method failed to bind listen socket, 
error 10048 (The specified address is already in use.).

Each multibridge connection of a SAS Stored Process Server is defined to start on a specific port, and this error indicates that the port for this particular multibridge connection is already being used by another process. Unfortunately the port number is not included in the error message.

If this is a new installation, then it might be necessary to select different ports for the stored process server bridge or multibridge connections. The default bridge port is 8601 and the default multibridge ports for a load–balanced stored process server are 8611, 8621 and 8631. You should check with your systems administrator to determine if the ports specified in your configuration are available on the stored process server host machine. The ports for the stored process server can be viewed and changed from SAS^® Management Console using the Server Manager plug-in by doing the following:

1. Expand the Logical Stored Process Server and highlight the Stored Process Server object. The Connection Name, Host name, Port and Protocol will display in the right–hand pane of SAS Management Console.
2. If you need to change a port number, right -click the Connection Name object you want to change and open the Properties.
3. Select the Options tab and change the port.
4. Click OK to close the Properties and save the change.
5. It will be necessary to restart the Object Spawner after making changes to the Stored Process Server definition in SAS Management Console.

If the stored process servers were functioning properly prior to receiving this error, it is likely that there are one or more stored process servers still running but they have become unresponsive and are orphaned processes. To restore the servers, follow step 3 "Evaluate SAS Processes After Terminating the Object Spawner" and step 5 "Stop Existing Stored Process Servers and Restart the Object Spawner" in SAS Note 30952 "Tips for addressing unresponsive SAS® Stored Process Servers, Part 1".
