This weekend we just upgraded from V5R2M0 to V5R4M5. Everything appeared to work ok. This morning, there is between a 26 to 30 second lag time from when someone selects an interactive program to run and when that screen or menu actually appears. The WRKACTJOB status for that user during this lag time says LCKW, lock waiting. There are no job or system messages indicating a problem. Does anyone have any ideas here?
