Closed as program error.
Error description
. When there is an application active on the system that is using the EZASMI sockets interface (includes EZASOKET calls, CICS Sockets API (not TCPSERVICE listeners), and IMS Socket API), if the SYSTCPIP CTRACE option SOCKAPI is enabled the potential exists for unrelated key 6 storage areas to be altered. Results if this occurs are unpredictable. Other symptoms: SYSTRACE and SYSOMVS CTRACE will show program interrupts occurring during socket processing but no errors reflected back to the application (or logged in the SYSTCPIP CTRACE). Some asynchronous calls do not log call completions in the SOCKAPI trace.
Local fix
. Do not enable the SOCKAPI option.
Problem summary
**************************************************************** * USERS AFFECTED: * * All users of the Communications Server for * * z/OS Version 2 Releases 2 IP : SOCKAPI * **************************************************************** * PROBLEM DESCRIPTION: * * When the CTRACE SOCKAPI trace option is turned on, * * unpredictable results can occur during application * * processing. Storage areas belonging to KEY 6 are overwritten * * causing erroneous outputs. * **************************************************************** * RECOMMENDATION: * **************************************************************** During read/and write asynchronous socket calls, sockapi trace entries are cut if the sockapi option is on. To collect information for the trace, an IOCTL socket call is invoked but the call is made in 64-bit addressing mode. The IOCTL socket call cannot be issued in 64-bit mode during asynchronous processing.
Problem conclusion
Code has been added to issue the IOCTL socket call in 31-bit addressing mode.
Temporary fix
