WSO2 Enterprise Integrator v6.1.1在使用VFS移动文件时生成锁定文件

Question

我正在使用 WSO2 Enterprise Integrator 6.1.1。我正在使用VFS从一个目录轮询文件并转移到另一个目录。但我的代理服务正在制作一个锁文件，无法移动文件。我最初认为这是一个文件权限问题，但当我尝试使用入站端点或我在代理服务中调用的自定义java中介时。然后文件成功移动。

锁定文件：

代理服务代码：

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="TestCSVFileMoving"
       startOnLoad="true"

       trace="disable"
       transports="vfs">

      <inSequence>
         <log level="full"
              separator=",========----------Test CSV File Proxy Triggered------======="/>
      </inSequence>

   <parameter name="transport.vfs.MoveAfterProcess">vfs:file:///opt/file/con/Out</parameter>
   <description/>
</proxy>

问题陈述：

我的问题是，在错误日志中，它清楚地表明它是一个只读文件。但为什么通过使用入站端点和调用自定义中介我能够移动文件。但是仅使用VFS我收到此错误？还有什么方法可以解决它。如果我必须使用VFS。
