Java OutOfMemory异常：加载zip文件时出现mmap错误 [英] Java OutOfMemory exception: mmap error on loading zip file

问题描述

我使用JVM参数在生产环境（rhel 5.2 x64，oracle jre 1.7_05，tomcat 7.0.28）上运行我的应用程序：

I run my app on production env (rhel 5.2 x64, oracle jre 1.7_05, tomcat 7.0.28) with JVM arguments:

-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

经过好几次有这样的堆栈跟踪：

After several time i've got stack trace like that:

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

查看我的探查器 - everthing没问题（堆和非堆内存使用10％），我不知道问题出在哪里。

Looking to my profiler - everthing is ok (heap and non-heap memory used for 10%) and i have no idea where is the problem.

这个公关oblem每天都在同一时间发生，并且与应用程序正常运行时间无关。导致问题的原因是什么？

This problem's happening every day at same time and it's not connected to application uptime. What is cause it problem?

编辑：

日志文件中的新输出：

Java HotSpot(TM) 64-Bit Server VM warning: CodeCache is full. Compiler has been disabled.
Java HotSpot(TM) 64-Bit Server VM warning: Try increasing the code cache size using -XX:ReservedCodeCacheSize=

java版本的问题。它在此描述： https://forums.oracle.com/forums/thread.jspa ？messageID = 10369413

推荐答案

我在用完资源（如耗尽资源）之前看到过这些错误空间或耗尽允许的内存映射。看看 sudo cat / proc / $ PID / maps | wc -l <​​/ code>与比较cat / proc / sys / vm / max_map_count

I have seen these error before when running out of resources such as running out of swap space or running out of allowed memory mapping. Have a look at sudo cat /proc/$PID/maps | wc -l compared with cat /proc/sys/vm/max_map_count

参见评论如下。

我还建议....

您似乎遇到了YourKit的错误。你使用的是什么版本？

You appear to have run into a bug with YourKit. What version are you using?

我会减少你的大多数选项，因为它们是默认选项，不做任何事情或可能使问题复杂化。

I would cut down most of your options as they either are the default and don't do anything or could be complicating matters.

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

我会尝试删除 -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。

I would try dropping -XX:+UseG1GC as well as this is a relatively new collector and shouldn't change your results.
