Your CICS region receives message DFHLD0002 A severe error (code x'0806') has occurred in module DFHLDLD. This occurs when running CICS Transaction Server for z/OS V2.3 with Compuware XPEDITOR/CICS.
A system dump shows XPEDITER/CICS module DBUGCXI using the XPI interface to do a RELEASE_PROGRAM for DBUGCXP. The release fails with code x'0806' (INVALID_ENTRY_POINT). Just prior to the release, DBUGCXI does an INQUIRE_PROGRAM. The inquire passes back an entry point of 00000000 and load point of 00000000. The release fails because the entry and load points are zeros.
