Seems this has happened before. We got a lorge, 4900 line, X-DEL job and LISTSERV started working on it at 15:03 today. At 16:25 it was still chugging away at it. I killed it for now. Files were backing up too fast. Should I expect it take this long? Probably so, even on a 3090/600. Should I send the requestor a note to break it up into smaller pieces?
