There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 19922944 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space
# The process is running with CompressedOops enabled, and the Java Heap may be blocking the growth of the native heap
# 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=
# JVM is running with Unscaled Compressed Oops mode in which the Java heap is
# placed in the first 4GB address space. The Java Heap base address is the
# maximum limit for the native heap growth. Please use -XX:HeapbaseMinAddress
# to set the Java Heap base and to place the Java Heap above 4GB virtual address.
