 ERROR DESCRIPTION:
 When using SSL to secure connections, TCP/IP Activity Blocks
 (ACBs) may not be freed.  These blocks will become orphaned and
 start to build up to the point where storage can be depleted.
 
 LOCAL FIX:
 
 PROBLEM SUMMARY:
 ****************************************************************
 * USERS AFFECTED: All users of the z/VM SSL server.            *
 ****************************************************************
 * PROBLEM DESCRIPTION:                                         *
 ****************************************************************
 * RECOMMENDATION: APPLY PTF                                    *
 ****************************************************************
 When configured to use the z/VM SSL server, the z/VM TCP/IP
 server may show a growing number of ACBs in use.  This may
 result in notifications that the ACB pool has been expanded due
 to depletion.
 
 PROBLEM CONCLUSION:
 When a secure connection is closed, there was a case where an
 allocated ACB was no longer needed, but never freed.  Code has
 been updated to correct this.
