It goes on and on. Just started now.

All plugins updated? Try to unload latest plugins you have installed and check when spam stop. If not try to start the server without plugins. If than stop you should find the plugin that cause that by unload one by one. This is what i would do.

Always a good idea. Found that bitch. :)
Thank you.
