我遇到以下关于异步（或单向）vm 入站端点的问题。在下面的测试中，似乎每个 vmconnector 的单向入站端点数量限制为 20 个。我的问题是：vmconnector 上是否有设置或以编程方式配置 vmconnector 以消除此限制的方法？
我正在使用 Mule 3.3.1 CE。
谢谢。
test1（将无法到达 secondFlow，除非第 21 个端点使用 vmConn2）：
<mule ..>
<stdio:connector name="stdioConn" messageDelayTime="1000" promptMessage="prompt >"/>
<vm:connector name="vmConn"/>
<vm:connector name="vmConn2"/>
<flow name="FirstFlow">
<stdio:inbound-endpoint system="IN" connector-ref="stdioConn"/>
<vm:outbound-endpoint exchange-pattern="one-way" path="path21" connector-ref="vmConn"/>
</flow>
<flow name="SecondFlow">
<composite-source doc:name="Composite Source">
