java heap space

[CreepersRule]

Everything is fine until I start my world and I get a white screen with white text that says "Shutting down internal server" and then my game crashes, but instead of "This mod crashed your game please delete it" or something like that, I got this:

 

The game crashed whilst registering texture
Error: java.lang.OutOfMemoryError: Java heap space

 

I'm not using any resource packs and have approx. 93 mods. (One of them is the Spectrite mod, which the latest version has 6,893 KB, hope this isn't causing the problem) What does this mean

But how? I started deleting some mods but is there any other way?

I switched Minecraft to run on 2 GB instead of 1, but now my worlds are lagging. (specifically in my survival world) Sometimes (more like always) the mobs freeze for a second and then kill me due to lag. I've had to delete a ton of mods because of this but nothing is working. What caused this unfortunate memory error to even occur in the first place? It didn't happen like a week or two from the date the topic was posted.

Funny thing you mentioned my mod, version 1.3.0 - 1.3.3 of the Spectrite Mod actually had a horrible bug that produced massive lag (a half-finished dimension that was cancelled due to being so laggy was unintentionally still being generated in the background). If your version is within this range, try updating it and your problem should go away.
