Error description
SMF 119 INIT & TERM records are going to different TCPIP address spaces in a CINET environment. Where multiple TCPIP address spaces are using the NMI SYSTCPSM to process SMF records.
Local fix
verification steps: The SYSTCPSM NMI is being used to gather FTP statistics in a CINET environment where FTPD is bound to all active TCPIP stacks. multiple TCPIP stacks are defined and active and each opens a socket and connects to it's own defined NMI AF_UNIX socket /var/sock/SYSTCPSM.tcpipx. The NMI application has separate subtasks doing each connect to one of the stacks defined NMI AF_UNIX sockets. FTP to the FTPD on TCPIP1s IP address interface the task with a connection to TCPIP1 NMI, gets a FTP server session init record. The actual SMF record shows the stack is TCPIP1 in the SMF TCPIP IDENT record. Close the FTP client session for the FTP on stack TCPIP1 and the FTP server session term record is processed, in the task connected to stack TCPIP2 NMI interface. The SMF record that is processed by this task sees the stack is TCPIP1 is in the SMF TCPIP IDENT record.
Problem summary
**************************************************************** * USERS AFFECTED: All users of the IBM Communications Server * * for z/OS Version 1 Release(s) 9, 10, and * * 11 IP: FTP server * **************************************************************** * PROBLEM DESCRIPTION: In a CINET environment with multiple * * stacks setup to use the SYSTCPSM NMI, * * the FTP SMF 119 TERM records were * * sometimes sent to the wrong stack. * **************************************************************** * RECOMMENDATION: * **************************************************************** In a CINET environment with multiple stacks using the SYSTCPSM NMI, the FTP SMF 119 TERM records were sometimes sent to the wrong stack. The information in the FTP SMF 119 TERM record was correct and has the correct stack name in the IDENT section of the record. The algorithm used to select the appropriate stack is different for CINET environment and that information was not saved in the session control block. +-------------------------------------------------------------+ + Please check our Communications Server for OS/390 homepages + + for common networking tips and fixes.

Problem conclusion
FTP server code has been modified to select the correct stack in a CINET environment. * Cross Reference between External and Internal Names
