Xfire客户端异常---Caused by: java.net.SocketTimeoutException: Read timed out

场景：

网络：客户端在同一个局域网中，所有客户端相对服务端来说是同一个IP地址。
服务端：使用axis1对外提供服务，具体信息不明（ws服务是别的公司提供）。
客户端：单个客户端无异常，当两个客户端一起跑的时候出现这个异常（两个客户端都会抛出这个异常，一个一直抛这个异常，无正确调用，另外一个客户端抛若干个异常，然后正常）。

异常：

个人猜测：

与这个网络场景关系很大，因为所有客户端共用同一个IP，而且异常还是出现多个客户端的时候产生的。

解决方案：

暂无（各位有什么思路吗）
