[REJECTED] Actions automatically interrupted!

[talosbane]

Some actions (interacting with an NPC or taking loot from bodies) are immediately and automatically interrupted (client warns me with "Interrupted" written in red).
It happens to me often and when this happens I am forced to close the client (even while I'm in a dungeon), I have to delete the "Cache" folder and I can re-enter in game but it seems that this is a temporary solution.

If this happens in a dungeon with other players, after deleting the "Cache" folder, client automatically brings me back to Stormwind (seems like I was stuck) and in that case I can not re-enter the dungeon.

Could someone help me please?

Thank you
