java - 回复 : java. lang.OutOfMemoryError:为 ChunkP 请求 32756 字节

Question

我一直致力于 java 项目功能增强。完成项目后，我可以将其部署到生产服务器中。但我在访问生产中的应用程序时在日志文件中收到此错误。我使用的是 tomcat 7，jdk 6update 16。

A fatal error has been detected by the Java Runtime Environment:

 java.lang.OutOfMemoryError: requested 32756 bytes for ChunkPool::allocate. Out of swap space?

  Internal Error (allocation.cpp:117), pid=17388, tid=38580

java.lang.OutOfMemoryError: requested 32756 bytes

启动时 JVM 内存设置是多少？

附加VisualVM 1.3.2 Tomcat启动时的进程。您将能够看到整个世代的内存布局、线程等。
