Problem summary
**************************************************************** * USERS AFFECTED: All * **************************************************************** * PROBLEM DESCRIPTION: CICS Trace does not report errno when * * a pthread create fails. * **************************************************************** * RECOMMENDATION: * **************************************************************** When CICS needs to create a new S8 TCB when calling system SSL CICS will issue a pthread_create. This will normally complete successfully. However, it can fail occasionally due to environmental circumstances e.g. hitting UNIX MAXTHREADS/MAXTHREADTASKS limits or hitting memory problems. If this happens CICS does not report the ERRNO returned from the pthread_create.
Problem conclusion
CICS has been changed to write a new exception trace entry which will report the errno received from a failed pthread_create. A new exception trace point, AP 1939, will report the errno value.
