It is important that the pdbfiles used to unwind the stack trace must match the exact OpenEdge release used: Version & Service Pack & Hotfix.
Progress PDB files can be used with the Windows debugger to unwind the C-level call stack when analysing memory dumps, which in a number of cases contains valuable information to assist with understanding and eventually resolving the problem under investigation. PDB files are symbol files for Windows-based executable's. Without these files, it's not possible to get a readable C-level stack trace from the OpenEdge executable's on Windows platforms.
