Problem Note 69198: A SAS® Scalable Performance Data Server might hold TCP ports in a CLOSE_WAIT state in AIX environments
 |  |  |  |  |
In AIX environments, accessing data stored within SAS Scalable Performance Data Server (SPDS) might leave TCP ports in a CLOSE_WAIT state instead of being freed. This behavior has been encountered starting with SPDS version 5.3.
A single LIBNAME statement that refers to a SPDS domain holds a port in CLOSE_WAIT for every access to the data. For example, a SAS program containing five steps that refers to the SPDS data has five CLOSE_WAIT ports after executing.
Freeing the SPDS LIBNAME might free and close the ports. Otherwise, the ports are not freed until the SAS session is terminated.
To determine the number of ports in a CLOSE_WAIT state on the system, issue the following command:
The CLOSE_WAIT port state is transitory and is normally short lived as conversations are terminated.
