EQA4015I Load module information could not be retrieved for module ModuleName because the loading service (provider) that loaded the module loaded it from a system managed library (e.g. LPA). The load module cannot be debugged.
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. Hence, z/OS Debugger cannot debug the module.
Programmer response
Contact your System Programmer and have them place the module in a non-system managed library.
