本文详细解析了JRE内存不足的多种可能原因，包括物理内存不足、Java堆内存设置不当等，并提供了调整Java堆大小、减少Java线程数及栈大小等解决方案，成功将服务器内存使用从默认的8G降低至1G，有效解决了内存溢出问题。

错误

错误如下，JRE内存不足。

解决方案

查看上述文件：

#   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.

首先查看服务器的内存肯定是够的，因此尝试减小了Java堆的大小，在/etc/profile文件中添加JAVA_OPTS

export JAVA_OPTS="$JAVA_OPTS -Xms1024m -Xmx1024m -Xss1024K -XX:PermSize=128m -XX:MaxPermSize=256m"

JAVA堆默认分配的最大内存为系统内存的1/4，我服务器内存32G,因此默认32/4=8G。现在为Java 堆分配的内存变成1G，问题解决。
