Error description
Abend S0C4 CSLSPC10+x'08C6. R15 is bad. ASID x'DC (user storage is used) not SCI storage. The error occurs, doing a MVCK, R15 initial value(x'608) is bad but not invalid. The first move is for 256 bytes. On the 2nd iteration (+x'100) R15 (x'708) then overlaps to unallocated storage. Unallocated storage starts at +x'800. The problem was traced to a zero route pointer. This caused an invalid route code to be placed into the route table.

Problem summary
**************************************************************** * USERS AFFECTED: All IMS V11 users using TSO SPOC * **************************************************************** * PROBLEM DESCRIPTION: Intermittent ABENDS0C4 encountered in * * module CSLULCM2 when issuing commands * * through TSO SPOC. * **************************************************************** * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF * **************************************************************** When a command is issued through TSO SPOC the CSLULCM2 module is invoked to process the command. During command processing CSLULCM2 attempts to access the command's route list prior to calling a tracing routine. To access the list an XMD pointer value is used. The validity of the route list pointer in the XMD is not checked, and if it happens to be 0, the S0C4 abend may be encountered when the invalid address is used.
Problem conclusion
GEN: KEYWORDS: *** END IMS KEYWORDS *** The CSLULCM2 module was updated. Namely, an additional check for the validity of the XMD route list pointer was added, so that if the value is 0, it is not used and the trace routine is skipped.
