SOAP请求-套接字读取超时

Question

I am using Muhimbi Document Converter Service for Document Conversion which is installed on a Windows Server. We have 2 Application servers which are load balanced. We are using the WSDL provided by the Muhimbi to create proxy classes so that we can connect with the conversion server. When we request for a conversion the SOAP request is framed internally somewhere through the proxy classes and is sent to the server.

When we started getting the Socket read timeout exception we started tracing the SOAP requests that are coming on the Conversion server and we found out the SOAP requests are coming from 2 different agents, sometimes the User-Agent is Axis2 sometimes the User-Agent is JAX-WS RI 2.1.4-b01 . The interesting fact here is only the requests where User-Agent is Axis2 are failing and causing a socket read timeout exception around 30 seconds in each case. The interesting fact is that somehow it's failing on 1 out of 2 loads balanced server, somehow one 1 server User-Agent is Axis2 and on another server its JAX-WS RI

I need help to identify that how its getting decided that whether user-agent should be axi2 or JAX-WS RI and is there any configuration at the JBOSS level which will make the connection alive until the response comes back.

I am also attaching the comparison of the successful SOAP requests , any help would be appreciated

关于我已经遇到的同一问题，我建议您在套接字读取超时的情况下使用wireshark或tcpdump跟踪您的请求和响应，这很可能是您在路由器，负载均衡器，防火墙等上进行了一些网络配置。导致在交换时丢弃某些数据包，从而导致socketReadTimeout。
