CLI0051 Invalid CICS Entry Point Table
The validation of the Entry Point Table used by the DBC/CICS Interface failed.
This error code is only received when using the DBC/CICS Interface. An eyecatcher in the Entry Point Table contains the characters "CEPT", used to validate the control block. The eyecatcher was probably corrupted by a programming error.
Take a dump of the CICS address space and contact Customer Support personnel.
