Question

我们经常在mule 3.4.2中获得Http连接器的连接重置异常。如何解决这个问题？

以下是我们用于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：

您可能正在达到文件打开限制;如果你看到一个＆＃34;太多的文件打开＆＃34;这将是一个迹象。错误无处不在尝试增加服务器的ulimit。
