Stabilizing Client program(XClint)
Weekly progress

• Problem 1. Memory leakage
• Memory occupancy is increased fast.
• Client becomes dead before 5 min.
• Problem 2. 100 of CPU occupancy
• Though idle state
• Whole PC system performance is declined
  tremendously.
• Solving 1. Release
• We found all pointers allocated dynamically by
  malloc or new.
• We made them released at the suitable position.
• Solving 2. Overriding function
• Visual C can override functions made by
  Microsoft.
• User must call the original function again at the
  end of overriding function.
• Other problem
• Client still becomes dead before 30 min.
