IDS 11.5 onpload exited abnormally during initialization

Hi, Has anyone encountered the onpload error "onpload exited abnormally during initialization" error using IDS 11.5?? Are there any suggestions for resolving this issue? The error happend on an HP-UX IA64 platform with IDS 11.50.FC2X2.??On?another similar server [same O.S and same Informix version] the HPL worked okay.? However on a second server the above error?occurs and no data loading starts.? The?HPL command being?executed is: onpladm run job load_batch_data_inactiv_U -p? A2I -fl -l test.log I have verified that the?load_batch_data_inactiv_U exists as a record in the the onpload database formats table, and the A2I project exits in the project table.??The server that is encountering the problem used to be the primary server in and HDR pair, but is now currently in a stand alone mode. Thanks, Bruce?
