Solved I cannot seem to be able to connect to my FTB Ultimate server.

[JohnnyX]

So, around 1 month back I created an Ultimate FTB server for me and my friends to play on. Suddenly, when I was playing about a week ago I lost connection and could not join again. My specs are: Windows 32 bit , 3GB ram.
I have FTB ultimate pack version 1.0.1 with ForgeEssentials installed . Whenever I try to join the server I get an error " Failed to connect to the server
Connection timed out:connect"
Also, I had just created my 3rd mystcraft dimension when I could not connect anymore.
PS: My server has Xms 1G and Xmx 1G.

Do you have error logs from both your client and the server? Is it just you, or everyone?

There are no error logs, just a popping up message. If there are any , where can I find them? Also for yur second question, others havent tried joining.

 

[jasonmicron]

How long has it been running? What changes were made before you noticed you couldn't connect? Linux or Windows?

The logs in question for your server would be in your server installation directory, and the one you'd most likely want to post here would be the ForgeModLoader-server-0.log.

My immediate thought jumps to a port not being forwarded correctly if you're trying to connect from another system and you are behind a home router.

My server has been running for about a month. I use windows and no changes were made. I believe that the server has been port forwarded correctly. i have included the server log.

Try removing those, unless you know of another reason why the server would be sending a stop command to your minecraft server after 17 seconds..?

Yes it received a shutdown command because i closed it after it oppened. The ForgeEssentials has bee nrunning smoothly so I dont know why It would cause a problem.

Reading around the interwebz, some sites have pointed to updating Java. Are you running JRE 32-bit or 64-bit? Have you attempted updating to the latest revision of JRE on your server?

Another note I read on that crazy internet on the Bukkit forums was someone suggesting configuring the keep-alive option on your router to send a keep-alive signal to your server. This basically sends a packet to your server every few seconds, and your server responds with a response packet indicating that yes, it is still there. That could be worth a shot, but if it worked before, not sure why that would be needed now.

I'll keep looking around. Hopefully someone else has seen this before, nothing jumps out at me in your logs other than what I posted above.

I have JRE 32 bit and no i have not tried updating , I ll do that now.

 

[Staxed]

start your server, try to log in a few times so you get the error, and the give us that log. If the error is happening during the login process, seeing that error in the logs is one thing we need to see.

The logs from your ftb client might help as well. Also, get someone else to try and login the server and see if they get it too (to make sure it isn't something wrong on your end) Sadly...I don't know exactly what path the ftb log is in...so someone else can post that hopefully . I'm not at home so can't check myself or I would.

 

[jasonmicron]

If you're running JRE 32-bit -- what are the hardware specs on your server? Are you running a 64-bit OS? It might be worthwhile to make the jump to 64-bit java. ... or not, depending on what you're running

I have a 32 bit OS yes.

Here is the most recent log.

One of your mods is causing a memory leak and crashing the server a few seconds after it starts. I know in single player this was an issue with RedPower at one time (a few threads about it), though I'm not sure what mods are causing it here as the log just doesn't detail too much sadly .

After you created your mystcraft age did you do anything in it? Place world ancher/chunk loader/etc?

From the errors it looks like something is caching the two worlds that thaumcraft is trying to unload. Finding what is doing that is the first step. I'm pretty new (only a few months) into FTB server management though, so I couldn't tell you what mod it might be, or how to figure out truthfully...hopefully someone a lot more knowledgeable can.

Though, I would search around (forum/google/etc) using the error below and see if you can find anymore information about it and ways to solve it on a server (most of what you'll find is single player based sadly, I don't have time to weed through all of it right now). "[SEVERE] [ForgeModLoader] Detected leaking worlds in memory. There are 2 worlds that appear to be persisting. A mod is likely caching the world incorrectly"

Well, I could not join even after redownloading the server and creating a new world. Maybe something else is causing the problem? Will I have to make a new world and start over? And to answer your question , no I did not place anything in the new age. Maybe the age was not stable? I wrote it so that it had iron , gold and diamond tendrills .

Well i found a way for the memory problems to stop but I had to delete the chickenchunks mod which i did not like. Also that solution of the world leaking still did not allow me to enter the server. Here's the video:

 

[Staxed]

Sounds like a question, but did you restart the server? If so...another log might help again...see if it's another error this time or still the same thing (if it's the same thing...then chickenchunks isn't the issue...)

So, any idea how to fix this based on the most recent server log? I Looked online but could not find anything simillar.

 

[Staxed]

Nope, I'm not sure...the log isn't showing what is actually making it crash sadly...

are you on a managed server? Possibly have your host look into it?
