RocketMQ：Cannot allocate memory

使用Storm本地模式消费RocketMQ数据的时候， 消费一点数据之后，就会出现如下错误：

Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000c7700000, 575143936, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 575143936 bytes for committing reserved memory.
# An error report file with more information is saved as:

尝试修改了RocketMQ的Broker内存大小，之后解决了这个问题。
