Hung CICS region
If a CICS® sockets application program using the Call Instruction API (EZASOKET) is erroneously link-edited without the EZACICAL stub, the entire CICS region might hang while waiting for socket calls to complete. Ensure that EZACICAL is explicitly link-edited with the application.
An EZASOKET call should generate a static call to the EZASOKET entry point within the EZACICAL stub. If the application is not compiled and link edited correctly, the EZASOKET call generates a dynamic call to program EZASOKET, which calls the socket API directly.
