Hello, I'm currently trying to run a modded minecraft client, but everytime I try to load a world it sits on the "Loading World - Coverting World" screen, and when it finally crashes I get this crash report:

I'm running about 24 mods. Earlier I was able to run 28 and I was playing perfectly fine, but then I tried adding 3 more - and all my troubles started. I removed them but I wasn't able to load a world, and eventually deleted my .minecraft and tried re-downloading them all again, but its not working even with less mods.

How can I properly allocate more space so I don't crash?

Is there a reason Minecraft is restricted to 1GB of memory? (-Xmx1024M) Chances are it needs more memory than 1GB. I typically give a modded client 3GB (your mileage may vary).

There isn't any particular reason why I have it that low but my JVM arguments are currently:
-Xmx1G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

do I just need to change it from 1G to 3G and that should solve my issues? Or is there more I need to do?

Edit: I just tried that and its still stuck on the loading screen...

Does the log show that the 3GB you configured is actually being set? If it is and you getting the out of memory error then I suggest that a mod may be having an issue. At this point its a game of removing mods until the problem stops. Chances are the last mod removed is the culprit.
