    When I start the Unity Editor and run my game, everything is fine and Unity Editor uses about 2.5GB of RAM. However, if I make some kind of change, for example change a script forcing a recompile, it will also redo the Global Illumination pre-processing, this leads to more than 10GB of RAM (all my available system memory being used). Any idea where I need to look to fix this?

    Your lightmap resolution is too high
    Higher lightmap resolution needs more RAM

    Though I wonder how come it seems to accumulate over time?

    Global illumination needs at least 16gb RAM for normal lightmap baking
