Abend with PO_REQINVS - Remote COBOL - PeopleTools 8.60

We just upgraded to FSCM PUM Image #50 and to PeopleTools 8.60 (from PT 8.58). Since the upgrade, we are getting a PERIODIC abend with PO_REQINVS (Build Inventory Demand). The abend occurs at PO_REQINVS.IS4200.GETROUTE (PeopleCode). The abend is happening with Remote COBOL. Here is the code: RemoteCall("psrccbl", "pscobolprog", "PTPECOBL", "AECOBOLPROG", "FSPTRTAE", "STATERECORD", "PO_REQINVS_AET", "PRCSINST", PO_REQINVS_AET.PROCESS_INSTANCE);

Looking at the COBOL trace, the error seems to be when the process tries to insert into table PeopleTools Table PSBATCHAUTH. A rollback occurs after the insert. Our workaround is to restart the Process Scheduler and then restart PO_REQINVS Application Engine. The process then goes to success.
