Explanation

An error occurred during processing by the contents supervisor. The error is probably a system error because errors that occur during the validation of user-specified parameter lists result in abend codes 206.

There are 2 forms of the dump title. For both forms:

SCC: System Completion Code (e.g. 0C4)
NNNNNNNN: Reason code for the SCC

In the dump title for failures within the nucleus:

FMODNAME: Failing Nucleus module name
NNNN: Offset of failure

Since CSVFRR primarily covers nucleus resident SVC code, if the failure occurs in a non-nucleus routine, it probably indicates a wild branch was taken.

The FRR routine CSVFRR issues the SDUMP prior to performing queue validation for the load list (LLE queue) and the job pack area (CDE and CDX) queues for the failing task, all of which reside in the LSQA. The areas dumped are SUM, TRT, LSQA, and SQA.
