Netty Epoll Server IO halting restart of server

While restarting my modded 1.10.2 servers, the console is spammed with “[02:45:49] [Netty Epoll Server IO #15/INFO] [FML]: Disconnecting Player: Server is still starting! Please wait before reconnecting.”

The #15/INFO part increments from 0-15 then restarts. Sometimes it only spams for three seconds, and sometimes it spams for upwards of 15 minutes. While it is spamming, no commands can be run other that ctrl + c to stop the server.

I’m not sure what to do here. I’ve tried removing plugins, but that doesn’t seem to work.

All help is appreciated.

Update: Most recent restart just hit the 30 minute mark for being stalled by spam.

I’m pretty sure that message is shown when a player tries to connect before the server is ready. Are you sure there are no players/bots trying to connect?

I cannot be 100% certain that there are no bots trying to join during that period, but no one is on the server before the restart and no one gets on after.
