我有个应用每隔几天莫名奇妙的是java进程突然内存占用高达7G多，然后jvm就会挂掉！ 通过分析gc日志，java堆，gc都很正常。报如下错误：

# A fatal error has been detected by the Java Runtime Environment:
#
# java.lang.OutOfMemoryError: requested 8589934608 bytes for Chunk::new. Out of swap space?
#
#  Internal Error (allocation.cpp:215), pid=12048, tid=1102043456
#  Error: Chunk::new
#
# JRE version: 6.0_22-b04
# Java VM: Java HotSpot(TM) 64-Bit Server VM (17.1-b03 mixed mode linux-amd64 compressed oops)

系统：
OS:CentOS release 5.6 (Final) Linux 2.6.18-238.12.1.el5

vm参数：
-server -Xms1g -Xmx1g -XX:+AlwaysPreTouch -XX:NewSize=384m -XX:MaxNewSize=384m -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:ParallelGCThreads=8 -XX:MaxTenuringThreshold=8 -XX:+DisableExplicitGC -XX:+ExplicitGCInvokesConcurrent -XX:+CMSClassUnloadingEnabled -XX:SoftRefLRUPolicyMSPerMB=0 -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintHeapAtGC -XX:+PrintTenuringDistribution -Xloggc:/opt/tomcat7_leaguelib-web/logs/gc.log

烦请各位指点，这个是不是触发了jvm的某个bug?

啊，这问题之前貌似见过。
如果这问题会稳定重现的话，试试加一个参数，
-XX:CompileCommand=exclude,org/apache/catalina/servlets/DefaultServlet,serveResource 来看看。

, 只是跳过会有点性能损耗呀.

http://bugs.sun.com/view_bug.do?bug_id=6973402

升级吧(不过估计还会有其他的问题...要不请学RednaxelaFX他们,自己编译JDK.自己打补丁..)

这个是jvm 在jit编译时出的问题吗？

我们有很多应用都跑在相同版本1.6.0_22的jre上，就其中一个经常性的出这个错，其他的都很正常！
