RMI: Socket timed out 引起的错误

[henrym]

我有一个rmi 的调用, 有时(但并不是总出现)会在rmi 客户端报下面的错误,造成程序失败:
java.rmi.MarshalException: error marshalling arguments; nested exception is:
java.net.SocketException: Connection reset by peer: socket write error
at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:122)
at net.zhongtong.platform.priorityqueue.fax.FaxServerImpl_Stub.sendFax(Unknown Source)
at net.zhongtong.platform.web.action.SendFax.send(SendFax.java:762)
at net.zhongtong.platform.web.action.SendFax.execute(SendFax.java:453)
at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:484)
at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:274)
at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1482)
at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:525)

后来.我在server 端启动脚本里设置了 -Dsun.rmi.server.exceptionTrace=true 参数,有时看到以下exception:
java.net.socketTimeoutException: Read time out

这个程序在以前一直没问题,最近才出现上述问题,是和网络有关吗? 需要通过设置其他rmi参数来解决吗? 求各位帮看看,不胜感激
