# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 8388608 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 Zero Based Compressed Oops mode in which the Java heap is
#     placed in the first 32GB 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 32GB virtual address.
