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。
