This subsection describes how to identify a request in which timeout occurred by using the trace based performance analysis, if a timeout has occurred while receiving the response in the redirector.

If a timeout occurs while receiving a response in the redirector, the KDJE41019-E message is output. The following information is output in this message:

• URI of the request
• IP address of the host in which the Web container used for communication with the Web server is running
• Port number of the Web container used for the communication with the Web server
• File descriptor of the Web container used for communication with the Web server
• Root application information of the trace based performance analysis

You can check where the timeout has occurred in a request in the trace based performance analysis, by comparing the root application information of the trace based performance analysis output in the message with the root application information output in the trace based performance analysis file.

You can check the request that is timed out with the trace information of the event IDs, described in the table below, of the request processing in which the corresponding root application information is output. Identify the corresponding request with the URI output to the operation name.

Table 7-13 Trace based performance analysis that you can use to check the request that is timed out

Event ID	Description
0x8000	This information is output after getting a request for processing the request. The URI of the request is output as an operation name.
0x8100	This information is output after the processing of the redirector finishes. The URI of the request is output as an operation name.
