# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 549581357056 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=

You are using g
instead of m
. Therefore, you get an error that the machines does not have 512 gigabytes of memory
That would do it ---
