The TimeOut directive sets the amount of time the server waits for a client to send its query once the client connects to the server. TimeOut also can set the maximum amount of time the server spends waiting for a client to accept information.
TimeOut time
time is the amount of time, in seconds, the server waits.
You can use only one TimeOut directive in the configuration file.
If you do not specify a TimeOut, the server assumes the following:
TimeOut 600
This sets the timeout to 10 minutes.
The following directive sets the timeout to 20 minutes, a useful time for large files on slow networks:
TimeOut 1200
