Server responded after timeout interval
A server request completed after the timeout interval specified by the application had elapsed. This can occur with a 3270 server or custom server which for some reason is not returning data within the time specified by the Timeout parameter of a ReceiveData state table action. The amount of time elapsed since the actual timeout is shown below.
If this occurs frequently, check the 3270 host network connections to ensure that they are available and that the response time is reasonable. If you are using custom servers, ensure that they are running and operating correctly. You may need to increase the timeout values to match the typical response time of the host system or custom server. If a state table action receives a timeout edge, it is the responsibility of the application to handle it in a sensible manner.
