• حافظه، فضای کافی برای تخصیص این حجم از حافظه را نداشته و سعی میکند با اجرای Garbage Collector، این حجم فضای مورد نیاز از حافظه را خالی کند.
• CLR تمام Thread‌های برنامه را متوقف میکند و Garbage Collector شروع به کار کرده و اشیا بلااستفاده «روی Thread ای که آن را فراخوانی کرده است» را Collect میکند.
