Disconnecting Issue

I keep getting disconnected for performing too many actions.
Most of the time I am just walking others I am using hollow form. Not pressing any other buttons at the time.
It only started after entering Act 4 and after unlocking Hollow Form. Not sure if that's the cause.

I've had the same issue, also with Hollow Form. It's happening almost once per map, and I'm just in level 1 maps with crap gear so I'm not activating some crazy action combo.
