When compiling a dialog in ADSC or running other tasks under CA IDMS/DC this error can occur:
DC027005 TASK:nnnnnnnn PROG:nnnnnnnn ABENDED WITH CODE UFFD AND REASON CODE 0248
For ADSC the program name will be ADSCDCOM.
This can happen after upgrading the operating system or other system software like the IBM Language Environment.
The UFFD (U4093) abend is issued by the IBM Language Environment (LE) runtime system. The reason code 248 indicates a mix of LE runtime modules from different releases have been loaded.
Release: IDADSO00100-18.5-ADS-for CA-IDMS
You may be using one of the older methods of LE support and copied some CEE load modules into the CA-IDMS libraries. To avoid this problem in the future you should use RHDCLEFE for LE support. To resolve the problem, check the load libraries concatenated to CDMSLIB for module names starting with CEE and either remove them or copy the version from the current LE runtime libraries.
