Board Thread:LotR Mod Technical Support/@comment-66.41.248.250-20160404203116/@comment-25330335-20160404223426

Well, Minecraft runs an internal server whenever you play it, even with singleplayer. So if it's shutting down, you've basically already crashed, so you can kill it. To allocate more RAM:

Find the profile you use to play LOTR Mod. Click Edit Profile. Click the checkbox that says enable JVM Arguments. Now, here is what should be in that box:

XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xmx1G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

Now find where it says -Xmx1G. Assuming that you have more than that much physical RAM on your computer, change the number 1 to 2. If you have more than four GB of RAM, try three or four.

Just select your vanilla profile and try to play without loading forge. No mods, no nothing.

Sorry this was delayed. I can keep helping all evening if necessary.
