#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 2147483648 bytes for committing reserved memory.
Java运行时环境的内存不足，无法继续，本机内存分配（mmap）未能映射8589934592字节，用于提交保留内存
解决办法，找到runserver.sh和runbroker.sh，编辑
JAVA_OPT=”$JAVA_OPT -server -Xms256m -Xmx256m -Xmn125m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m”
改成如上就可以了
