BIP9241
Severity
20 : ErrorMessage
An internal error occurred with a DataFlowEngine address space, returncode <insert_0>, reasoncode <insert_1>.Explanation
An internal error occurred processing a semaphore whilst starting or stopping a DataFlowEngine address space. '<insert_0>' and '<insert_1>' are returned from a semaphore function call.Response
Investigate the return and reason code as to the cause of the problem. See z/OS UNIX System Services Programming Assembler Callable Services Reference and z/OS UNIX System Services Messages and Codes. In some cases, errors can occur because the semaphore system values IPCSEMNIDS, IPCSEMNOPS and IPCSEMNSEMS are incorrectly set. The command DISPLAY OMVS,L displays these system values, and they can be changed dynamically using SETOMVS. See z/OS UNIX System Services Planning for further information. Contact your IBM support center if you are unable to determine the cause of the problem.
