Problem summary
**************************************************************** * USERS AFFECTED: All users of the IBM Communications Server * * for z/OS Version 1 Release(s) 10, 11, and * * 12 IP: Enterprise Extender * **************************************************************** * PROBLEM DESCRIPTION: Enterprise Extender CSM 4K ECSA storage * * leak processing EEDIAG,TEST=YES. * **************************************************************** * RECOMMENDATION: * **************************************************************** Enterprise Extender (EE) CSM 4K ECSA storage leak processing EEDIAG,TEST=YES. The storage leak occurs when the EE endpoint is IP connected via the IUTSAMEH (SAMEHOST) link. The EE probe response is built in a 4K CSM ECSA buffer allocated by the EE endpoint TCP/IP stack. The CSM ownership of the buffer is assigned to the TCP/IP routing stack when the packet is forwarded over the SAMEHOST link. The TCP/IP routing stack fails to copy the CSM token when the packet is received over the SAMEHOST link, thus preventing the storage from being returned to CSM when the packet is forwarded to the IP network. This problem can only occur when running in a Common INET (CINET) environment with two or more TCP/IP stacks active and interconnected via the SAMEHOST link. +----+ +----+ | EE | | EE | +----+ +----+ || () || +--------+ +--------+ ( ) +--------+ | TCP/IP |---IUTSAMEH---| TCP/IP |---( )---| TCP/IP | +--------+ +--------+ ( ) +--------+ () D NET,EEDIAG +-------------------------------------------------------------+ + Please check our Communications Server for OS/390 homepages + + for common networking tips and fixes.

Problem conclusion
EZBIFINB has been amended to copy the CSM token associated with the buffer containing the EEDIAG response packet when it is received over the SAMEHOST link. * Cross Reference between External and Internal Names
