Failed to handle packet #66

Closed mjl1010 closed 9 years ago

Hi, I use ProtocolLib-3.5.0-SNAPSHOT.jar (Build #269) and I experimented an error when I die:

[21:34:16 INFO]: mjl1010 lost connection: Internal server error

I use CraftBukkit 1.7.10, thanks for reading.

This is caused by some other plugin accessing the Bukkit API (or Minecraft itself) from a wrong thread. I doubt this is due to ProtocolLib.

It's often difficult to determine which plugin is to blame, though. A plugin could detect these violations (like my own DetectCME), but it often only works in very specific cases.

If you can't find such a tool, I suggest simply disabling plugins until you no longer get this error. Then the last disabled plugin must be the culprit. You can also speed this up by disabling more than one plugin at a time.

Thank you very much for your reply so precise, this error occurs because of the Residence plugin, I use the version of the plugin 3.0.0.0Dev.
