Sophie suggested that they check the event logs and system reports to see if they could find any clues. After some digging, they discovered a pattern: every time the error occurred, it was related to a specific library, WD27COMM.dll .

When developing enterprise applications with PC SOFT's WinDev 27, encountering unexpected crashes, memory leaks, or application freezes is an inevitable part of the lifecycle. While WinDev provides an excellent integrated debugger, production environments rarely offer the luxury of live debugging. This is where memory dumps come into play.

-ma : Write a "Full" dump file, including all process memory (highly recommended for deep analysis). 4. Analyzing the Dump File

If you are investigating performance issues rather than crashes, use dbgSaveMemoryDump (or dbgSauveDumpMémoire ). This function generates a file showing memory usage, allowing you to see which elements are consuming memory without needing a live debug session. You can also generate this type of dump during a debug session by pressing Ctrl + Pause . Conclusion

Days turned into weeks, and the team was no closer to solving the mystery. The error persisted, and productivity suffered.
