Ok so I tried everything (changing IP to static, reinstall Java, set Java priority to high, connected with cable, disabled firewall and anti-virus software, updated all drivers etc.. ) and also my ISP swears my parameters are good.. They did order a connection check by their staff, but that will take a looong time probably..
But this thing I found suggests that there might be a problem on the server side towards me..
"Connect to the server with your client, and run in a single direction, as more and more chunks are loaded into ram, the server will continue to eat up RAM, when its ran out of RAM, the server is stopped. On the servers console you'll get a memory error (java.lang.OutOfMemoryError).
Any clients connected to the server will lose connection (Since the server has stopped). And their clients will display them the java connection lost error message. "Internal exception: java.net.SocketException: Software caused connection abort: recv failed"."
That is the error I get the most, that means error might be from server to me? But it's odd how only I have that problem :/
Anyone know more on this subject? Playing is painful like this.. I get disconnected all the time every few minutes sometimes a bit longer or shorter
ps This happens to me on both Vanilla and FTB Unleashed
