The Change Memory Settings action is available starting from IntelliJ IDEA. # M means Megabyte, G means Gigabyte. Invalid heap size Another scenario when the "invalid heap size" issue comes while restarting JVM is when you configure 64 bit JVM to accept the memory of more than 4GB but it's running on a 32-bit data model. Java memory allocation for User Auth service or Kerberos Auth service: xmx=1g. Change the Maximum Memory/Ram option to allocate more RAM as the default for all ATLauncher instances. -Xmx) is less than 32GB. SincerelyFaust. if the value of -Xms and -Xmx is same JVM will not have to adjust the heap size and that means less work by JVM.
