Question

我的系统中安装了elasticsearch 2.2.0和logstash 2.1。

当我使用以下命令执行logstash的配置测试时：

sudo service logstash configtest

它出现以下错误：

 There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 55545856 bytes for committing reserved memory.
# Possible reasons:
#   The system is out of physical RAM or swap space
#   In 32 bit mode, the process size limit was hit
# Possible solutions:
#   Reduce memory load on the system
#   Increase physical memory or swap space
#   Check if swap backing store is full
#   Use 64 bit Java on a 64 bit OS
#   Decrease Java heap size (-Xmx/-Xms)
#   Decrease number of Java threads
#   Decrease Java thread stack sizes (-Xss)
#   Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.

解决这个内存错误的最佳方法是什么，因为有很多规定的解决方案？

此外，

I have bootstrap.mlockall : true in elasticsearch.yml configured.

我们可以不同地配置elasticsearch位吗？

Answer 1

我通过将ES_JAVA_OPTS传递给一个较小的值来解决我的问题，我认为默认情况下它会尝试将机器的整个内存分配给它（在我的情况下是2GB）并且它会失败。
