Direwolf 1.6.4 Server Problem

[amichal002]

Hey all, i wanted to create server in a Direwolf20 1.6.4 pack, so i downloaded the server via launcher but i encountered a problem. Whenever i run the ServerStart.bat file, it starts loading for a seconds, but then it hits some kind of a wall and stops, waiting for me to press random key to close. I copied the text from the command line, but i noticed there are some symbols missing, anyways its in the first Spoiler. There is a file ForgeModLoader-server-0.txt that gets created after the command line closes, but im not able to upload it due to the length limit. If requested, i can copy it in the following post. I have tried different version of the pack, such as 1.0.18/19/25, but none of them worked. I tried to find a fix, but i havent been successful much. If anyone has an idea what could it be, please say it. Thank you for you help.

Do you see a folder under the minecraft folder called crash reports?
Check there for a crash report.

Are you running this on your home computer? If so, how much ram do you have? How much is allocated to the server?

Try java 7

Already tried that, it seems that the .bat file starts only if i have Java 8 installed

There is no Crash reports folder. And sorry about that RAM, i forgot to write that earlier. I have 8GB RAM, and to the server is allocated 2GB. I've run some ftb servers in the past, about an year ago and it worked without problem, so i think it wont be in the RAM

 

[amichal002]

I hope i fixed it. The problem was indeed in Java 8. The way i did it was, i had installed Java 8 before. The ftb launcher ran on it, which caused nothing wrong i think. But the server didnt work. So i installed Java 7 and unistalled Java 8. But then the command line wrote something like this when started: Java has value 1.7 but value 1.8 is required. The problem was, that even after uninstalling Java 8, some files didnt get removed. It was java.exe, javaw.exe and javaws.exe in System32 which caused the problem. Dont know why they didnt get removed. So after removing these files manually and installing Java 7 again the server booted up properly.
If i find any more problems, i'll write here. Thank you all for the help.

No worries

You may find that 2gig for the server to be a bit low. I'm not sure. I know to play 1.7 packs, 3-4 gigs is recommended for your computer to get any kind of smoothness.
