Internal Exception: java.io.IOException: Error while write(...)

Do you get more detail in the log files?
Connection reset by peer means your server has gotten some sort of error or a reason to send back to the player's client an RST packet, which basically means kill the connection immediately.
This can happen if the player is using a client that sends some kind of information that the server does not expect to receive. Tt can mean many other things.

 

Could you please post a full error log, with many examples of it occurring? Is it always the same exception? Do you see this happening when something has been modified, ran, installed? Thanks.

 

I get pretty much same thing.

This may or may not work, but I've had luck with changing java (on my dedi) from openjdk to the webupd8's oracle java, and updating to the latest build of spigot.

 

On latest spigot.

Whats is the huge dif in java? I would also assume someone from spigot could maybe clarify what Java to use or if it should matter?
anyone jdk or web?

 

http://stackoverflow.com/questions/...cle-jdk-and-open-jdk#comment27153592_17364418

 

Thank you! Honestly! I will install soon and report if it is fixed.


EDIT: updated and testing now.

I ran this "sudo apt-get install oracle-java8-set-default" then "-java version" to check installed.
So far so good. we will see.

 

Still same issues.

Are you running a proxy server using Bungee? I am not sure but it might be an internal issue when connecting to an other server. Or it could be a MySQL error when reading something that requires information from the game.

 

I do not use bungee.

 

Issue is still around.

See Error and look, you will see the following.
I can not seam to find the cause. This may not even be server side but can not find any more info on this issue. Hope this can help to resolve it. If I find a fix or gets fixed in a update I will post again.

I saw the "[08:39:31 INFO]: You are running the latest version", but what version of client do you have? I can definitely say it's the server not accepting the request when trying to look over your information (Checks to see if your account is real and stuff). I know this happens using Bungee, but you clearly said you're not using Bungee. Hmm. Pretty much to explain what's happening, java.io is a package in the jar file of spigot (bukkit and all those other jars). What happens is when you join a server, this package which is from http://netty.io looks for information, mostly packets that are read and sent to the server. It checks what version your server is running, if it corresponds to your client's version, if your account is real, checks the UUID and IP and so on. I am not an expert on the topic, but my guess would be from the new Spigot build you are running, which is maybe not fully compatible with some of the information netty expects.

Here is what I suggest you do:

1) Check your client version. Try downgrading it to an older one and see what happens (keep logs)
2) Downgrade your spigot back to the last one you last build before this new update and again, run some tests and keep a log trace.
3) I am not sure about this one, but your firewall and/or VPN might be preventing some of your information to be sent from your client to the server, thus triggering an exception.

Again, those are the things I would do. I am not an expert at all, but I know some things. Do correct me if I'm wrong.

I hope this helps.

 

#1: It does not happen to me so not sure how I would track the client....
#2: Dont believe I can do such a roll back at this point. To many plugins updated.
#3: this I can check.

I do keep logs and nightly backups of the entire server in full. Just hard to pull a roll back.
Its also not seaming to be consistent. So that makes it also hard to track.
Its pretty easy to find the cause if its always happening and specific timings, thats seams not to be the case though.
I will keep a eye out. An there was more 1.8.7 updates so maybe Im not the only one with this issue.
An may already be getting resolved. Never know.

 

Try asking some of your players having this issue to use the same client version you are on. Which would be the latest I assume. Ask them to see if that fixes the issue.

 

I will ask them when, if I can.
I use 1.8 on 1.8.7 cuase I use shaders and I dont get the issue myself.

Thanks for yoyur help.

 

@NullBlox did you ever find out what was causing this issue? I've been having the same problem for a good three weeks and I can't determine what is causing it.

 

@Disc @PirateCraft @NullBlox Do you use any plugins from this author? From looking at this topic it seems like the issue often occurs through his plugins. The OP mentioned VBOs were his issue. If you have them on, turn it off and try it again.

 

I do not know the cause.
Its not the VBO settings. I never touched those and they are currently off.

This happens when you /kick player, also happens when NCP kicks for suspect hacks, and when my server's wrapper kicks them on the restarts.
So it seams to me to be something with how plugins are handling /kick

I can reproduce this by loggin in and using console to /kick myself.

[20:44:14 INFO]: CONSOLE issued server command: /kick zach
[20:44:14 INFO]: [Bank] Saving Bank for UUID to file

So.... Im not a coder but its Kick that is seams to create the issue. Hope that helps to fix this issue.
An if I find the fix I will report. Also On current Spigot.
