Ye i can be very annoying and you just get say 5x failed messages and I wondered where all my ammo went + more decay of course when the game spring back into life and your left half dead. Its clearly not an easy problem to fix I guess only thing I could suggest is when I get teh new update it fragments my drive or until I defragment the drive at least but I wonder if they ever defrag the servers I think it could help somewhat.
