More frequent than what? 5.2? 4.x? We have been running 4.4 for a couple of years, and 4.7 for a few weeks on some systems, with no problem such as this. When we do see a freeze it's related to the server or network, and unless the problem goes on for quite a while, the clients all recover when the problem goes away.
