Hello I seem to be getting this issue, it's fine for awhile but when we get over 6 −8 users it crashes the server then restarts on its own. I have looked at the same issues but none of them are mine in the fact I don't have mine query on same with r-con, also other people have said it's a modded client as much as that could be true I don't think that's my issue here, when the server has one one online it still comes up with this message roughly every 5 minutes. I think the only thing I could do is check through all my plugins one by one. 28.02 09:49:03 [Server] SEVEREat net.minecraft.server.NetworkReaderThread.run(SourceFile:76) 28.02 09:49:03 [Server] SEVEREat net.minecraft.server.NetworkManager.c(NetworkManager.java:265) 28.02 09:49:03 [Server] SEVEREat net.minecraft.server.NetworkManager.h(NetworkManager.java:149) 28.02 09:49:03 [Server] SEVEREat net.minecraft.server.Packet.a(Packet.java:71) 28.02 09:49:03 [Server] SEVERE java.io.IOException: Bad packet id 81 Anyway thanks in advanced.
probably caused by one of the following: someone entering your server iport in their web browser a service like mcstats, checking your server
Bertware MCServerStatus? It doesn't need a plugin nor Mine-query even though it's optional, could it be that? http://mcserverstatus.com
I did read somewhere that you can use it without that plugin, but that missing this plugin might cause such errors. However, that error is nothing to worry about
