Minecraft Forums

I keep receiving this error or similar randomly from things such as scrolling to the bottom of the inventory etc and even just walking around, also for some reason it wont let me allow more memory to minecraft. No matter what i put in the JVM via edit profile i still can only use 455 MB of my 16GB RAM. I have tried using the -Xmx1G etc both in the launcher and even to try allowing java more via control panel. I have several mods installed (~27) and can supply the list if needed. Any help to resolve this would be greatly appreciated.

P.S Sorry if i didnt do anything correctly as far as the error report goes, im new to the site.

Look at this.

Emphasis added.

This is a weird bug that I've seen recently. Something adds that second Xmx argument which overwrites your own settings. I hear completely wiping (make a backup of your saves, mods and config folders) and reinstalling Minecraft might fix this.

Nope, didn't work :c I even re-installed java as well. Is there any way to trace where the command comes from? It is doing it on even the vanilla (though not crashing cause vanilla doesn't use that much memory). Thanks for the suggestion though. I can only think that it is coming from either minecraft or java.
Also where would i locate the file in .minecraft that specifies/reads etc the jvm flags? perhaps the answer can be found there.

That I don't know. You might try using Magic Launcher. It adds it's own memory arguments that usually overwrite whatever was set by the user.

thanks again, and ill give magic launcher a go.

1Gb should be enough, try adding

-XX:MaxPermSize=512m

Quote from grimallq

The problem here is that whatever you set in your JVM arguments, an extra "-Xmx512M" gets added at the end by something and overwrites the previous arguments.

^^ indeed. I can confirm that magic launcher fixes this problem, thank you so much for your help
