An error occurred during processing by the contents supervisor. The error is probably a user error because errors that occur during the validation of user-specified parameter lists result in abend codes 206.
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.
Note that if this dump title is received, there is most likely an LSQA shortage in the address space in which the error occurred.
