Forge 1.12.2 server can´t start

My forge 1.12.2 server can´t start, but when I try the same configuration and mods in a server done by me in my computer it works. I think it´s probably RAM. I have been testing and I need only one GB. Is there a way I can get more RAM? Here is my log. https://mclo.gs/FttozRx The farthest I have come was post inicialization of thaumcraft

here I have another log. The server stops always randomly https://mclo.gs/eEHDXJc

SO, what would you recommend?

I will ask some friends to decide what mods to remove. Thanks!
