"You have been disconnected"

[DrRick]

Over the past couple of weeks I've frequently been experiencing the "You have been disconnected" black screen while playing (not while zoning). After 5-10 seconds I get booted back to the character selection screen. From there, I can immediately log back in on the same character, so it's not a full LD. It seems to happen only once about 10-15 minutes into a play session. After I log back in I'm good to go and can play for several hours without it happening again. It's really painful when it occurs in the middle of a fight though. Any thoughts on why this might be happening?
