Due (I think) to a bug in the request processor 404s end up putting a list of values into the start time variable which caused this bit to fail and not clear out the old data. Here was the debug [-conn3-] Error: return: failed to redirect '404': exceeded recursion limit of 3 followed by [-sched-] Debug: JCD: ds_sweep_data: name:4.start nsv:1026036712 1026036712 1026036712 1026036712 when the ds_sweep_data proc was run. Probably should catch the whole statement to insure that the cleanup is more robust but it is all treating the symptoms not the disease (RP).
