Server Crash - Golden Conductive Pipe

[shopkeeperf56]

Hi there...

Been playing on a private server with a friend all weekend and have gotten really far but have just had our server crash when attempting to connect Golden Conductive pipe to a Blast Furnace (Crash report below).

Any ideas on how i can backtrack the server or even just delete all the conductive piping from the files or somthing like that to at least enable us to get back into the world?

Can upload world files if it will help.

Thanks heaps :-D
Will be super sad if i loose this one.

you can delete the conductive pipe thats causing the problem whit mc edit

 

[Moasseman]

Known issue, do as philip said and use one of the world edit programs to remove the conductive pipe.

This crash happens when you try to connect a (golden?) conductive pipe to a GT machine.

 

[shopkeeperf56]

thanks a lot guys!

will give that a go

 

[Moasseman]

I gotta correct myself: This crash happens when you connect a conductive pipe to a GT machine that doesn't have the kinetic generator upgrade installed.

I'm getting this error now and I know it's because of the conductive pipes and GregTech machines. Is there anything a server admin can do to prevent or fix this?

It's possible to prevent the crash from happening by removing BaseMetaTileEntityMJ.class which is found inside the gregtechmod.zip in the mods folder, but that also removes the MJ compatibility.

I'm having this problem on our multiplayer server...hosted by a hosting company. I tried removing that file, re-zipping, and putting it back in and it doesn't load the world....just hangs. Am I doing something wrong? Also, how do you unload those offensive chunks via MCEdit? With the original GregTech Mod, it'll load the server but within about one minute it crashes. I've even tried loading real quick and breaking the conductive pipes and the Gregtech machine...doesn't work.

When you are loading in "real quick" and breaking the pipe the server has already crashed. You just don't see it for a minute before you disconnect. The server side crash is instant as soon as a chunk with the offending pipe is loaded by someone entering that chunk.
You will need to download the world to your PC. Edit it with MCEdit to delete the pipe, then upload the world back to the server.
If you are running MCPC+ and WorldEdit AND your player is not in the chunk that crashes, you can do it from within game using WorldEdits //pos and delete commands to remove the 1 block.

If not, all you can do is MCEdit it out.

 

[DanOfEarth]

Thanks for the feedback. Unfortunately I can't find a nice tutorial even on youtube to show me two things:
a. How to unzip the remote "world" and access it with MCedit
b. If successfully opened, actually find the offending block within MCedit and remove it. (I suspect I might figure this one out if I can navigate over to the block though.)

I've downloaded MCedit, have the world zip unzipped in a folder...and can't put the two together. I see my one single-player-world in the MCedit "recent worlds" directory, but can't navigate to my FTB ultimate file.

The tutorials out there are atrocious. If I can figure this out, I'm going to put together an "Idiot's Guide" on how to fix this issue as well as use MCEdit with FTB files.

 

[Gerald Huppertz]

I use a hosted server so I had to access it via FTP using Filezilla.
My word file is not zipped, I just downloaded the entire folder.
MCEdit looks into the default Vanilla minecraft install location for Worlds so C:\Users\{Yourname}\Appdata\.minecraft\saves
(I could be missing something in that structure, at work right now)

But you need to put the entire world folder (not zipped) into the saves folder.
Then MCedit should see it.

Once you have it loaded you can literally fly around using the WASDQZ keys to the corrupted pipe. Select it, delete it. Hit CTRL-S to save
Then upload the files back to the server.

Thank you. That worked! I even managed to find the three supposed chunks, deleted them and uploaded server. It was still crashing. It's tripping over a task in the API gregtech folder. I guess deleting the chunks themselves wasn't enough.
