Rockstar has said you should erase your game data and reinstall Grand Theft Auto IV if your PS3 freezes during gameplay.
The US PlayStation forums picked up on the issue and linked the problem with 60GB launch models of the console.
One commenter called the technical support lines and followed the steps above and has had no problems since.
This problem seems to be far from common, with only a tiny portion of the Internet reporting issues; the official European PlayStation forums make no visible mention of it.
