Hi Paul, Thank you for your response.
This issue has been observed in z/OS version 2.5 and later. I am currently discussing it with the z/OS platform team. As a workaround, we installed a signal handler for SIGPIPE that invokes _exit(141). Once the final changes are determined, I’ll propose a fix upstream.
