EQA4018E Load module ModuleName was loaded from LLA. A load module by the same name was found in a data set found in file DDName. However, the lengths of the load modules did not match.

Explanation

z/OS® Debugger uses binder APIs to retrieve necessary information for the debugging of a load module. When the load module is loaded from a system managed library the binder APIs cannot retrieve this necessary information. In this case, a module by the same name and but with a different length was found in the data set(s) allocated to the specified DDName. Because the lengths do not match, that module cannot be used by the binder APIs and, therefore, the load module cannot be debugged.
