java JVM 内存溢出 64位JDK
新产品发布，拿来试用。由于本机是win7_x64，但是为方便工作，机器安装了从32位的JDK1.5一直到64位的JDK1.6的4个JDK。为保证运行时能与大多数人的运行状况相同，依然采用了32位的jdk1.6来运行产品。
结果，我第一次碰到应用服务器刚起来就crash的问题。
生成的JVM的错误日志如下：
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 678096 bytes for Chunk::new
# 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:317), pid=2468, tid=2708

# JRE version: 6.0_31-b05

发生问题以后，再次启动AS，使用jconsole监控，加os的资源管理器查看，一切看起来都非常正常。单单从错误日志来看，是内存不足导致JVM的carsh。
启动参数：-server -Xms1024M -Xmx1024m -XX:MaxPermSize=128m
但是，本机有8G内存，运行此应用时，仅仅用了不到3G，试着使用-Xmx加大内存，试着提升到1600M，但是，无法启动，最终定位在1200M，但是，AS依然会在运行一段时间后crash。
接下来就是各种google，有人说这是jdk1.6的bug不过人家的小版本号是25（甚至还有某些号称某电商的人，建议回滚至update24版本），我这是31，难道这个bug一直没有关闭？关于这个问题在StackOverflow有一篇帖子（http://stackoverflow.com/questions/6344546/java-6-update-25-vm-crash-insufficient-memory），问题跟我一样，并且采用了各种办法貌似是最终解决了。
楼主在启动时加上了-XX:-DoEscapeAnalysis参数，但是我这依然不可以，这个参数貌似是不再分析可能的溢出，我这只是将crash的时间稍微延后了一些，问题依然没有解决。
再查看此帖的后面，说是降低-Xmx的大小，而且在jvm的崩溃日志中也提到降低-Xmx/Xms的大小，于是试着降低大小，并且把as启动时的jvm参数全部去掉，使用默认值。问题竟然解决了（但是，根据官方说明，-Xmx的大小缺省应该是物理内存的1/4，在我这也就是2g，这个值比我设置的参数要大，只是指定之后就出问题），从目前来看，as运行了半小时依然没有问题（开始时是1分钟以内自动crash）。但是，在实际的生产环境中，JVM默认的参数，往往不能满足需要，因此，就出现一个问题：既然操作系统已经安装64位，并且JDK有64位版本存在，生产环境下尽量在64位的os下安装使用64位jdk，从而把性能发挥至最优。
关于为何要降低jvm堆的大小，有以下说明：
JVM线程堆栈
应用程序中的每个线程都需要内存来存储器堆栈（用于在调用函数时持有局部变量并维护状态的内存区域）。每个 Java 线程都需要堆栈空间来运行。
根据实现的不同，Java 线程可以分为本机线程和 Java 堆栈。除了堆栈空间，每个线程还需要为线程本地存储（thread-local storage）和内部数据结构提供一些本机内存。
JVM堆栈大小
-Xss 128k：设置每个线程的堆栈大小。JDK5.0以后每个线程堆 栈大小为1M，以前每个线程堆栈大小为256K。根据应用的线程所需内存大小进行调整。
在相同物理内存下，减小这个值能生成更多的线程。但是操作系统对一个进程内的线程数还是有限制的，不能无限生成，经验值在3000~5000左右。
JVM heap与JVM私有内存、JVM线程堆栈大小间的关系及平衡。
线程栈的大小是个双刃剑，如果设置过小，可能会出现栈溢出，特别是在该线程内有递归、大的循环时出现溢出的可能性更大，如果该值设置过大，就又影响到创建栈的数量，如果是多线程的应用，就会出现内存溢出的错误．而对于此问题的解决，还有另外一篇文章http://www.blogsoncloud.com/jsp/techSols/java-lang-OutOfMemoryError-unable-to-create-new-native-thread.jsp，此文依然是介绍让降低JVM堆分配的内存。
