Java OutOfMemory异常:加载zip文件时出现mmap错误

Question

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:

-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

经过几次,我有像这样的堆栈跟踪:

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

期待我的探查器 - 外观是可以的(堆和非堆内存使用10%),我不知道问题出在哪里.

这个问题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.是什么导致问题？

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.

Answer 1

我以前在耗尽资源（例如耗尽交换空间或耗尽允许的内存映射）时见过这些错误。看看sudo cat /proc/$PID/maps | wc -l与cat /proc/sys/vm/max_map_count

请参阅下面的评论。

我还建议....

您似乎遇到了 YourKit 的错误。您使用什么版本？

我会减少您的大部分选项，因为它们要么是默认选项，不会执行任何操作，要么可能会使事情变得复杂。

-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，这是一个相对较新的收集器，不应该改变你的结果。
