有jvm参数导致jvm在jvm启动时创建一个hprof文件

Question

我们的一个测试人员在启动我们的应用程序时，在他的Windows环境中不断收到一个创建的hprof文件。

• hprof文件只显示在他的Windows实例上。其他测试人员看不到这个
• hprof文件每次启动时都会出现。
• hprof文件非常小（45mb）。没有OutOfMemoryErrors或hprof文件中对此有用的任何内容。
• jvm不会退出
• 该应用程序在启动后对其安装非常有效。

有其在启动创建一个HPROF文件，可以在启动时指定的（在这种情况下，通过一些环境变量）的一些JVM参数？我知道如果你指定cpu = samples，它会在退出时创建一个。

我有理由相信这是一个系统设置。但我不知道哪一个。我们正在运行Oracle的jre 1.6_024，并且jvm作为tomcat 7启动的一部分运行。

更多信息此处为我的SET OUTPUT。
