Solution: RTY only supports Java 7. If you are not using it, then get it. No, Java 8 does not count as Java 7.



Problem/Crash: I log on to the server and is disconnected shortly afterwards. After that, the server goes down for a bit.
Solution: You're in or near a corrupted chunk. Bug Remi to move you. Please keep all post of request for moving in this thread.
I'll add to this list as more problems emerge.

So, what if your problem wasn't on the list? Follow the steps bellow and post a message in this thread.

1. Make sure you're problem is not already listed.
2. Make sure that you aren't making some mistake. Many times when people think they have encountered a bug, it's actually functioning just as intended.
3. Make sure you are able to reproduce the problem.
4a. Submit the Crash log to me, either vie the forums here, or trough some other site like Pastebin.
4b. If the problem isn't associated with a crash log (like disconnecting from the server) please post a detailed description of the problem here, and the steps to reproduce it.
5a. If you don't get any crashlog, check MinecraftLog.txt in the FTBLauncher's folder. There will always be a crash log here.

Thanks katrix
I'm gonna find problems in RTY and go bug you to fix them :^D

Also, I wonder if you know why the server crashed when I tried to enter the temple?
Entering through the sides of the main entrance didn't crash it but entering straight forward crashed it.
I need to find the crash log if I possibly have one

[Remilia Scarlet]

If it's that weird entering the building thing, it's doubly weird because the server doesn't generate a crash log whenever the server goes down because of it. What might be worth doing is catching me when I'm online and doing the crash as I'm watching console so I can see exactly what's going on. As it is right now, I have no clue what the heck's causing the crash since... well, I'm not at the console when it happens and I don't have any crashlogs to work with

[Suzzie2]

I don't use the mod-pack. It lags horribly for me.


I have Java 6 Does that affect anything...?

[Remilia Scarlet]

Java 6 is so old you can't even download it from java's website anymore...

[Nuclearblt]

Java 8=Java 6 with a fancy title
Besides that erm.... The problem with the fortress was with a mod that "dun fucked" according to remi
Also tainted biomes crashed me and satori if you stay in it, probably a corrupted chunk (no pun intended)

[Katrix]

@Nuclear

Nope, not corrupted chunks. It's something about the world tick.

[Remilia Scarlet]

Java8 = Java6 if you ignore the hundreds of improvements, bug fixes, backend changes and other general "updates"

Just like how Minecraft 1.8 is the exact same as 1.8 beta if you ignore all the improvements, bug fixes, backend changes and other general "updates".

[Suzzie2]

Java 6 is so old you can't even download it from java's website anymore...

WAT.

But...I've had it for only a year...

Technology
Outdated as soon as you get it.
Applies to programming as well.

@Gman

So, let's go trough a few steps.

1. Does this happen with any other server?
2. Have you been able to get one before this?
3. Are you able to reproduce the problem with a good amount of time in between attempts? (not 5 minutes)

[Nuclearblt]

So, as of late, I've been playing some RTY and I've noticed that the server is down. When do you think it will be back up?
