Player already online

hello, I run a large community, and I reboot the server every 8 hours or so a lot of the time, this error happens:

[14:12:39] [Server thread/INFO]: Disconnecting GameProfile{id='xxxxxxxxxxxxxxx', name='Xxxxxxxxxxxxxxxxx'} (/xxx.xx.xx.xx:xxx): §cThe player §dconnordude229 §cis lready online.

and no one can join the server when it does, rendering the server useless

Has this been happening before? or did it just start happening.

And, when you remove the reboot plugin does it fix the problem?

It happens if I use a plugin or not.

It happens without a restart plugin.

Are you running the latest versions? Do you have a script restarting the servers? If so can you post your script? Is it logging into the server that restarted, or the whole network? The amount of information you have given is insufficient for us to help you solve your problem.

Not running the latest versions (Im running compatible versions, so thats not the reason) It happens if I do it: manually, scripted, via multicraft, via plugins.

Logging into the restarted server.

The amount of information you requested was already (mostly) stated.

Anyone have any ideas?

You mentioned Multicraft, are you running JLilyPad(allinone) or GoLilyPad?

And, lets keep this on one thread, no need to have the same conversation twice.

I don't recall posting this twice, sorry for that

Ok, so lets clarify some things about your setup.

Your running your proxy and connect server on a vps or dedicated server, and all you other servers are set up through Multicraft? Your running the latest versions of everything, Proxy, Connect, and Bukkit Connect? And your running the latest version of Spigot/CraftBukkit?
