Error description

Local fix
Issue TERMAPI before terminating the subtask.
Problem summary
**************************************************************** * USERS AFFECTED: All users of the IBM Communications Server * * for z/OS Version 1 Release(s) 13 IP: * * Sockets API * **************************************************************** * PROBLEM DESCRIPTION: Subpool 0 key 8 storage allocated by * * EZBSOH03 not freed when application * * subtask terminates without issuing * * TERMAPI call. * * The orphaned storage eyecatcher in * * the dump looks as follows: * * EZBSOH03 DYNAREA CELL PO. * **************************************************************** * RECOMMENDATION: * **************************************************************** Module EZBSOH03 is called by an application subtask as part of TCPIP socket processing (e.g. EZASMI or EZASOKET). EZBSOH03 proceeds to allocate a dynamic storage area in subpool 0 key 8. This storage area remains allocated until the subtask issues a TERMAPI call. If the subtask is attached with the SZERO parameter (subpool 0 storage shared), and the subtask detaches without first issuing a TERMAPI call, then the EZBSOH03 dynamic storage area does not get freed until the application main socket API task is terminated. This can lead to a slow growth of subpool 0 key 8 storage over time. +-------------------------------------------------------------+ + Please check our Communications Server for OS/390 homepages + + for common networking tips and fixes.

Problem conclusion
Changes have been made to the sockets API modules to release user autodata storage when the task terminates. * Cross Reference between External and Internal Names
