java调用webservice服务org.apache.axis2.AxisFault: Read timed out问题

shihp 2016-05-09 05:04:40

环境：
1、服务端aix 1.4的webservice，可用域名或ip访问，访问的客户端必须在服务器上注册，注册分配给客户端权限串且绑定IP
2、调用webservice服务的客户端代码是用axis2 1.6写的，客户端程序部署在11台服务器上（10台linux、1台windows 2008），使用客户端的程序是一个独立运行的socketserver程序，每个客户端都是在服务器上注册的，未经注册的不能访问。
3、服务器每天有两个时间段不能正常提供服务，会出现调用超时或失败的情况，但其它时间服务器可以正常工作的。
4、客户端设置的超时等待时长，小于服务器返回数据的最大时长，即：服务器保证30秒内返回数据，但客户端的超时时长小于30秒，如20秒。
现象：
现在是有的客户端调用时正常，数据能正常返回，成功率近100%，且延时在几秒内，但有的客户端调用经常调用超时或完全超时，经常不成功的成功率在50%左右，且只是在某一时间段内，过了这一时间段就全正常了。
尤其是完全不成功的，即使重启客户端服务器也不管用。
