Linux系统引起java.net.SocketException: Broken pipe的原因？

Question

有两台linux服务器A、B
系统版本都是 Red Hat Enterprise Linux Server release 6.0 (Santiago)
JDK版本都是 1.6.0_29
在A端发布一个RMI服务，配置如下

<bean factory-method="setProperty" class="java.lang.System" lazy-init="false">
    <constructor-arg value="java.rmi.dgc.leaseValue"/>
    <constructor-arg value="300000"/>
</bean>

<bean factory-method="setProperty" class="java.lang.System" lazy-init="false">
    <constructor-arg value="java.rmi.dgc.gcInterval"/>
    <constructor-arg value="900000"/>
</bean>

<!--接收数据服务(下层模块提交的数据)-->
<bean id="eventProcessor" class="com.dataservice.EventProcessorImpl"/>

<bean id="rmiEventProcess"
   class="org.springframework.remoting.rmi.RmiServiceExporter">       <property name="serviceName" value="dataservice/eventProcessor" />
   <property name="service" ref="eventProcessor" />
   <property name="serviceInterface" value="com.dataservice.EventProcessor" />
   <property name="registryPort" value="${registryPort}"/>
   <property name="servicePort" value="${registryPort}"/>

B端为客户端，配置如下

<bean id="rmiEventProcessorClient" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
    <property name="serviceUrl" value="${targetAddr}" />
    <property name="serviceInterface"
        value="com.dataservice.EventProcessor" />
    <property name="refreshStubOnConnectFailure" value="true"></property>
</bean>

情况是这样的，B端在调用A端发布的服务时，间歇性的出现如下异常。

补充：相同的程序，放在linux版本相同，JDK版本相同的服务器C去调用A不会出现以上问题，B、和C的防火墙策略是相同的，防火墙关了也会有这个问题，就算把服务端部署在B，B内部调用也会间歇性出现该问题。

奔溃了，搞不定啊，求解。。。。

最后一个办法，tcpdump
抓包。
tcpdump -Xs 0 -i 网卡名如eth0 -vv -w a.cap port 端口号
