在 mule 3.4.2 中，我们经常收到 Http 连接器的连接重置异常。如何解决这个问题？
下面是我们用于 HTTP 连接器的代码。
<http:connector name="HTTP" cookieSpec="netscape"
validateConnections="true" sendBufferSize="0" receiveBufferSize="0"
receiveBacklog="0" clientSoTimeout="10000" serverSoTimeout="10000"
socketSoLinger="0" doc:name="HTTP\HTTPS">
<receiver-threading-profile
maxThreadsActive="400"
doThreading="true" poolExhaustedAction="WAIT"></receiver-threading-profile>
<dispatcher-threading-profile
maxThreadsActive="400"
doThreading="true" poolExhaustedAction="WAIT"></dispatcher-threading-profile>
<service-overrides sessionHandler="org.mule.session.NullSessionHandler" />
</http:connector>
我们得到的例外是：
