Sometimes when running application under Delphi 2009 debugger, as soon as I do anything

  • 0

Sometimes when running application under Delphi 2009 debugger, as soon as I do anything with the application form (click, move..) Delphi starts to flood Event Log with following messages (similar):

Module Load: UNKNOWN_MODULE_59954.No DebugInfo. Base Address: $02D90000. Process MyApp.exe (5584)
Module Unload: UNKNOWN_MODULE_59954. Process MyApp.exe (5584)

Number of UNKNOWN_MODULE increases for each cycle, so at example there have been almost 60000 module load/unloads.

Application remains unresponsive during this flood. Sometimes I have to just terminate the application to be able to continue.

Any idea how to start tracking the cause of this?

    As “Arioch ‘The” suggested – download and run Sysinternal’s process explorer.

    • From the View menu choose “Lower pane -> DLLs (Ctrl+D)”
    • Mark your process in the process tree
    • Right click lower pane’s header and choose “Add Columns”.
    • From the DLL tab choose “Base Address”.
    • Sort modules on that column
    • Find your dll’s base address – you will get it’s name 🙂

    If the module is unloading too fast – set “Options > Difference Highlight Duration” to 9 sec.

    In my case it was odbcint.dll:

    procMon - find unknown module

    Also give your PC a virus scan – just in case 🙂
