本文介绍了如何解决在Web容器中遇到的RC: 10054错误，该错误表明远程主机强制关闭了现有的连接。通过在Web容器的HTTP传输设置中增加ConnectionIOTimeOut参数到30秒或以上，可以解决此问题。此解决方案适用于6.X和7.X版本的应用服务器。

was 6.X
To solve the problem, increase the ConnectionIOTimeOut parameter for your Web container HTTP transport. The default value is 5 seconds. You can increase the value 30 seconds or greater. Set the value using the administrative console. Click Servers > Application Servers > server_name > Web Container > HTTP Transports > port_number > Custom Properties > New. Type the following property name and value:

* Name: ConnectionIOTimeOut
* Value: 30

was7.x
Servers > Application Servers > server_name > portlet container > Custom Properties > new

已修改，待运行一段时间看看（运行2天）；
确认，不再出现。
