With 100 minutes, there is something wrong in the "flow" or "concept".
You can't put a timeout of 100 minutes because the server should release the request and don't keep variables in memory or cache. The server performance will drop and you can have "server not responding", with the need to recycle or restart the server!
Imagine you have 20 connections in 100 minutes, all will be kept during this time but there are other timeouts: session timeout, script timeout, execution timeout... and they are different, less...
