I haven't had them since Early Access but now, since 2.1, I get one about once a day. Usually while in a instance. My game seems to freeze on me a lot less than before... So i guess it's kind of ok tradeoff. I'm usually back in time before my party decides to kick my arse for d/cing too long.

I could never find out the cause of my freezing and have no idea what's up with the 90k error either. I'm fairly certain it's related to the game or client in some way though, as nothing has changed on my computer or about my internet connection since 2.1. Yet one problem appears while another mostly vanishes.
