[ERRORLOG]Game crashes after 9-20 seconds, Ubuntu 14.04 LTS

try this line to start the server sudo java -Xmx2G -Xms128M -jar server.jar

could be a video card driver problem by the looks have you installed the lateist drivers??? problem with linux is very poor drivers and they dont often update

This looks indeed like a problem with the graphics card driver. Please install the latest Nvidia driver, there should be a newer version available. Eventually it could also be related to 32 bit, then you can try different start parameters, but you should try to update the graphics driver first

Thanks for the reply!
I've successfully installed the latest Nvidia drivers for my GPU. The problem still persist. Here is the newest errorlog.

thanks yeah if your upto date with video card drivers if i was you i would reinstall ubuntu with the AMD64bit OS not the 386 32bit i know it says AMD64 witch can confuse someone with a
intel cpu but the AMD64 is just the name oO, it will work fine with your i5, infact it will work far far better, i have helped another user who also had video card errors do this and it solved his problems he also installed 64bit java witch he thinks helped too

go here to see what this guy did he had same problem and we solved it Can't create world 10/12% bug

When the issue still persists, it may be related to 32 bit as mentioned. Updating to 64 bit as @yahgiggle said definitely makes sense if you have more than 3.5 GB RAM installed.
Alternatively you can try to change the launch parameters of the game: Go to the Steam library -> rightclick on Rising World -> Properties -> Set Launch Options and try the following lines (if the first one does not work, try the next one etc):
+memory 768 768
+memory 768 512
+memory 1024 768
+memory 1024 512
+memory 512 512

Thanks for the info on the linux OS bit confusion, I did not realize that, rather stupid to name it
AMD but I guess some people just wants to see the world burn.
May this be the cause that any game I play on linux lags? (not fps lag, just twitching and weirdness.)

been that the cpu is a 64bit cpu and the fact that 32bit only alows for 4gigs of ram max to be used and the fact the data can move more free, the 64bit os is a far batter option for smother running and faster computer so its a win win
even if this does not solve your problem you will sill see improvements making it a good option.

Indeed I did! And the game is working now.
Thank you so much for your responses

thats awesome news so just for others what in the end do you think solved your problem ?

Glad to hear it's working now! Basically it's always beneficial to use 64 bit instead of 32 bit, especially when you have more than ~3.5 GB RAM installed.
About the amd64 architecture, it has "historical" reasons^^ https://en.wikipedia.org/wiki/X86-64
