Every time I try to open my tekkit classic server this message pops up.

Error occurred during initialization of VM could not reserve enough space for object heap

Error: Could not create the java virtual machine

Error: A fatal exception has occurred. Program will exit.

I don't undertand what it means so if anyone knows what it means contact me asap. Thank you for your time.
