Disconnecting when destroying items

Hi,

I recently came back to playing and I use an addon that destroys gray items when picked up when I auto loot, however I keep getting disconnected. I noticed that the disconnects happen if the addon deletes more than 2 gray items at a time. Unfortunately there is no way to make it delete them one by one, and I clearly remember that when I used to play 6-8 months ago that never happened. Is there a reason for these disconnects and is there a way to fix it, as it get quite annoying to either get disconnected every 2-3 mins or manually deleting lots of items.
