Crash in my FTB server

[Plasimodo]

Hi everyone, this is my first time making a modded minecraft server and I could really use some help. My server started crashing after my friend and I explored a bit, now everytime i start the server it crashes. Things were going great for the 4-5 hours we stayed close to spawn but now the server won't stay up long enough for us to connect

The error in the crash log is as follows:

Allocate a bit more ram to your server, try around 3-4gb

Post new log if it still fails, and please use paste.feed-the-beast.com and share the link here.

I changed the server to run on four gigs. I noticed, however, that not all of the mods included in the FTB Infinity Evolved are working properly on my server, is there anything I can do to fix this? I'm not sure where i may have went wrong, but playing on the server i created and playing in a solo world using the mod pack are drastically different.

Thanks a lot for the help
