My minecraft crashes when logging in server

Server goes on, I try to get on it, crashes, the thing is, I've been able to get on the server before with the mods and everything, I don't know what's happening, help please.

Here's my server log: https://mclo.gs/IP73lLh , it says the server is overloading or something like that.

I can't open my client log, it says it's too long for every program I try to open it with.

Thanks
