Packages being dropped or exceeding timeout.The documentation on DecoderException suggest that it happens when the receiving party is unable to rebuild the data being sent. On one occasion I attempted to kick the player when this was happening and instead the following appeared in the chat as if I had said it: It does not really help to discard what is going wrong. However, the player remains on the server and they remain in the tab menu. When this occurs, I (as admin) can do the kick command and it says successfully kicked. Sometimes, but not always, the player will leave the server but their player model remains on the server. When they interact, other players can see the interaction immediately, but the affected player does not see the intended action for 10-20 seconds or so. The player can open chests and break/place blocks. I want to stress this point: the source of the network problem might not be the network. The player used to have no lag issues, but I cannot think of anything that has changed since it started about a week or so ago.I have tried adding more RAM to the server (8 gigabytes in total now).We have tried destroying all signs on the server (Googling the Java error gives results about this being the problem on 1.8~ Spigot servers but I doubt this is the problem).We have tried restarting the host router.We have tried setting the firewall level to "lax" on the host router.
