JavaFX application crashes during GC.

I have a Java FX application that crashes sometimes during a garage collection. It's not consistently reproducible. This is from the hs_err_pid file:

Heap:

Looks like the eden space is full. The intial heap size is set to 6 gigs, with a max of 27 gigs. Should I increase the initial heap size or would that just be a bandage for a bigger problem?
