I have experienced temporary freezings (they unfreeze after a while) in certain areas.
Perhaps this is just on my computer but my game always freezes for a short period when I run into an area on any server with a certain placeable, which is the "Weeping Willow" tree found in Southeast Bezantur behind Temple of Sune.

I think that is you're local files, I personally have only in very rare cases crashed on the server (Mostly caused by my cabel..) I suggest trying a re-install or perhaps googling the issue, usually there are people with similar problems in the world.
