After upgrading CA Symdump CICS r 9.1 from CTS 4.2 to CTS 5.2 the client receives the following error messages when some dumps are captured.
CASD7418 Recursive XDUREQ and
CASD7436 IN69SYMZ unknown failure
The client forgot to use the CA Symdump CICS 5.2 RDO entries as part of the upgrade. The client was using the CTS 4.2 RDO entries.
The client migrated the CTS 5.2 table entries and removed the r 4.2 entries which resolved the problem. The table entries are located in PDS HLQ. CABAJCL(CSDSYM69).
