Tony, >> server uses just one subtask for this function.
So what you are suspecting is that the DU-AL (of the task) or the PASN (of the partition) you are doing this from did change. Very unlikely- but wait: could this be a multiprocessing issue? Maybe it only fails if the return-process is dispatched on a different CPU.... Enough speculating for me: You have a system-dump at time of failure to return the data? -- Martin Pi_cap_CPU - all you ever need around MWLC/SCRT/CMT in z/VSE more at http://www.picapcpu.de
