[1.7.10] server - NoClassDefFoundError

[xert7xainsf]

Hi so I am running a forge 1.7.10 server (installer/version: forge-1.7.10-10.13.3.1355-1.7.10-installer )

I am using a .bat file to launch the server here is the code:

-------------------------------------------------------------------------------

java -Xms4G -XX:MaxPermSize=4096m -jar forge-1.7.10-10.13.3.1355-1.7.10-universal.jar -o true nogui

pause

-------------------------------------------------------------------------------

But I keep getting this error code:

-------------------------------------------------------------------------------

-XX:MaxPermSize=4096m

 

That's wrong. Try 64 or max. 128m..

Ignore what that other guy said about the MaxPermSize, you're doing that fine. I am pretty sure that the issue is that you are either missing some server libraries, or you are trying to run client side mods on the server.

Hi,

thanks for the help I figured what he said wasn't true as i use the same code for other servers.

as i am kinda an idiot can you tell me which of these are client mods (these are the mods i am running)

1. If you set the MaxPermSize too high, the java garbage collector needs more time - So normally you can choose a high number and lower it (half the amount everytime), till you get an error (not this error). Then just double it and you have the perfect amount (normally it is 256m, but not more than 2048m!!(and that's rare))

2. Optifine is causing the trouble....

 

And sorry, that I was telling you something wrong...
