Right now Minecraft will only start if I have the -Xms1G JVM argument; if I try to increase it, I get the error: Error occurred during initialization of VM Could not reserve enough space for 2097152KB object heap. It sounds like either I don't have enough RAM available, or there's a program keeping Minecraft from taking up that much RAM. However, I have 8GB of RAM, so I have way more than enough. Does anyone have any ideas on what's keeping me from increasing the amount?

Generally, when I need more memory for Minecraft, I set the max heap and not the min heap. For example; java -Xmx2G -jar minecraft.jar you could also set it like this: java -Xms1G -Xmx2G -jar minecraft.jar Avoid allocating too much RAM since that will starve the rest of the machine.
