The RMF™ control block STGST (pointed to by field CVTMFCTL in the CVT) and the trace table are helpful in determining the cause of the error. The SDWAVRA contains module trace information and pointers to the STGST, IOCHT, IODNT, LCUT, HSARB, SCHIB, and IOSB. The failing CSECT name and the error condition can be determined from RTM2WA and SDWA.
