I've been wasting my entire day off trying to fix minecraft... It crashes once a second player joins. I've tried different versions of java. I've tried taking off many mods. What's going on?

Bump... No one helps out here :/

Go to pastebin.com and paste your entire crash log on there, then give us the link to it.

So I think I figured out the problem mod... but in the process I switched to java 8. I switched around to other javas trying to make it work, eventually I stuck with java 8... but now I can't use arguments and my game starts lagging when I play 2 players. Any suggestions on improving java 8 performance?

How bout some logs? Like copy/paste of launcher log+game output after you've been playing a while and lagging.

Thanks for actually replying, guys. I went back to java 7 and just used previous arguments. I think I'm fine now. I could not find any arguments that worked with java 8. And yeah I think the initial problem was Armormovement. Luckily I seem to be able to run both orespawn and specialmobs along with mo creatures without a problem. I was worried that was it.
