OK this is something i've wanted to post since is has been really annoying and frustrating. For the past 3-4 days now i have been been getting a lot of lag and getting kick for Internal exception: Java.net.socketexception: Connection reset nearly every 5 minutes now f=and when it does happen i am unable to join the server agin for at least another 5 minutes. It is getting very very frustrating now that i'm about to give up. I'm not sure what to do, if i have to update my lwjgl.jar files or its the server because i know my internet is perfectly fine.
Does it happen only if you are on Main Island on alice? For me, it does... and there is already a thread about this problem. Go here: http://www.skcraft.com/threads/alice-has-returned.593/page-2. Updating the JLWGL files does help (for at least one of us), link here: Update JLWGL.
It's worth trying what MadNess suggested. I do think it has to do with the server, but that should be resolved this week or so.
In that case, your best bet is waiting for the server move (which appears to be very soon). Patience is key here Hopefully it will pay off!
