Java OutOfMemory异常：加载zip文件时出现mmap错误

我运行我的应用程序生产env(rhel 5.2 x64,oracle jre 1.7_05,tomcat 7.0.28)与JVM参数：

-xms8192m -Xmx8192m -XX:MaxPermSize=1024m 
-Doracle.net.tns_admin=/var/ora_net -XX:ReservedCodeCacheSize=512m -XX:+AggressiveOpts -XX:+UseFastAccessorMethods 
-XX:+UseStringCache -XX:+OptimizeStringConcat -XX:+UseCompressedOops -XX:+UseG1GC -Dcom.sun.management.jmxremote 
-Dcom.sun.management.jmxremote.port=9026 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

几次之后,我有堆栈跟踪：

Java HotSpot(TM) 64-Bit Server VM warning: Attempt to deallocate stack guard pages Failed.
Java HotSpot(TM) 64-Bit Server VM warning: Attempt to allocate stack guard pages Failed.
mmap Failed for CEN and END part of zip file

看着我的分析器 – 一切都很好(堆和非堆内存用于10％),我不知道问题在哪里.

这个问题每天都在同一时间发生,它没有连接到应用程序正常运行时间.原因是什么问题？

编辑：

日志文件中的新输出：

解决方法

之前我已经看到这些错误,当运行的资源,如运行的交换空间或运行的允许的内存映射之前.看看sudo cat / proc / $PID / maps | wc -l与cat / proc / sys / vm / max_map_count进行比较

见下面的评论.

我也建议….

你似乎遇到了一个与你的Kit的bug.你使用什么版本？

我会削减大部分的选择,因为他们是默认的,不做任何事情或可能会使事情复杂化.

-mx8g -XX:MaxPermSize=1g -Doracle.net.tns_admin=/var/ora_net 
-XX:ReservedCodeCacheSize=512m -XX:+UseG1GC -Dcom.sun.management.jmxremote.port=9026

我会尝试放弃-XX：UseG1GC以及这是一个相对较新的收藏家,不应该改变你的结果.
