JVM 崩溃 Failed to write core dump解决办法 WINDOWS

MIT

key words: JVM,崩溃，windows，Failed，core dump，虚拟内存

最近从平台中分出了一个小项目，没有配置单独的服务器，而是需要部署到公司网站服务器（windows server）上去。

一共部署一个网站，一个设备通信服务jar

阿里云ECS 4G 内存，系统：windows server 2008 SP1 64位未激活

一开始查看了下java环境变量，设置得非常乱，上面装了两个java，一个64位一个32位，但是path指向的都是32位的java。

通信服务jar能够顺利启动，不过隔三差五就挂掉，报JVM异常

tomcat 一开始启动就不顺利，重新设定了JAVA_HOME才启动，后来也没过几天又挂掉了，后来再也启动不了了。。。。。

当时直接在bin目录生成的日志hs_err_pid1234.log内容是：

#

# There is insufficient memory for the Java Runtime Environment to continue.

# Native memory allocation (malloc) failed to allocate 32744 bytes for ChunkPool::allocate

# 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.

#

#  Out of Memory Error (allocation.cpp:273), pid=2620, tid=4872

#

# JRE version: Java(TM) SE Runtime Environment (8.0_45-b15) (build 1.8.0_45-b15)

# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.45-b02 mixed mode windows-amd64 compressed oops)

# Failed to write core dump.

....以下省略超多jvm异常

不外乎说内存不够，64位的OS 没有用64位的java，减少java 线程数，等等之内的，但是我看了下任务管理器，线程数也不多，4G物理内存，才用了1.2G

没办法，只好把java全部卸载，重新安装64位版本的。重新设定JAVA_HOME和PATH，发挥JAVA最大功效。还是没好，然后又把盗版系统激活重新，还是没好

最后，我在通过运行DxDiag 查看系统信息时才发现问题：

一开始的System Information：

其中Page File: 3908MB used, 184MB available ，184M，太小了，然后到C盘查看隐藏文件，居然没发现pagefile.sys文件。

也就是没有设置虚拟内存。。。。。

设置完虚拟内存后：
