Question

我遇到一个问题，Java webapp中运行的Tomcat会导致很多java.lang.OutOfMemoryError错误，但是没有生成堆。

我通过CATALINA_OPTS

启用了setenv.sh中的以下标记

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/path/to/

这之前已经奏效，但出于某种原因，现在还没有。

通常我会在Dumping heap to /path/to/heap/dir/中看到catalina.out，但不是这次。

从ps

的输出可以看出，VM选项最为明确

堆目录有足够的空间和写权限（我认为实际上记录了这种IO异常）

由于XSL Transformation通过taglibs发生了很多JSP，导致OutOfMemory。

Stack如下所示：

我试图理解，在什么情况下OutOfMemoryError不会触发堆转储。

提前致谢。

使用-XX时不会生成堆：+ HeapDumpOnOutOfMemoryError
