Here is I think a relevant discussion of this topic:

The 35Gb is 1/4 of the physical memory of 145Gb, which is the default
MaxHeapSize


java -XX:+PrintFlagsFinal -version | grep HeapSize
    uintx ErgoHeapSizeLimit                         = 0              
{product}
    uintx HeapSizePerGCThread                       = 87241520       
{product}
    uintx InitialHeapSize                          := 2147483648     
{product}
    uintx LargePageHeapSizeThreshold                = 134217728      
{product}
    uintx MaxHeapSize                              := 32126271488
