    VanishNoPacket has memory leak. I had this plugin too and memory just increase. When I remove this plugin memory is stable.

    Did you record any data on this? I would be interested in your information.

    I can confirm it what he said, I have 24h graphs of my server's memory usage with and without VanishNoPacket enabled, and VanishNoPacket does cause it to just keep going up. I didn't save screenshots of the graphs because it was a personal test to see what was causing it, but I can redo the experiment and send you the graphs if you need them. To be fair, I also tried it with VanishNoPickup and it had a memory leak as well.

    Makes little sense for VanishNoPickup to have a memory leak, from how minimalist it is in handling data. That's... special.

    I'll look into memory stuffs in VanishNoPacket this week or next.
