If the exit address value in the RCVT is a valid LPA address, you can use services such as IPCS or TSO TEST to locate the entry point address of the named RACF exit routine and the corresponding exit address in the RCVT. Use these services to identify the owner of the routine that the value in the RCVT points to, and then determine if the difference is expected. If the difference is not expected, use a facility such as SLIP to interrupt the routine that is modifying the named RCVT entry, and determine the reason for this difference. For information about exit addresses in the RCVT, see ../com.ibm.zos.v2r1.ichc400/ich2c410.htm.
