Crashing Problems

Every day or hour my garrysmod crashes or my friends garrysmod crashes. Not sure what happened. Listen closely, im not crashing alone. When we play on a random server and play there like an hour then your garrysmod instantly crashes. It says CUtlRBTree overflow! Is it an update or a bug? Please reply if you know the solution.
