Hi Matt, I'm Ccing the ML since the answer can interest everybody here.

I mean that the content of the map is read from a flat file. If you modify running map, HAProxy only updates its memory, not the flat file. So after a reload, if the flat file does not contain same content as HAProxy's memory, then updates are lost. > What I add this was is added to memory and not to the file ? exactly > So, I need to sync the file with the memory in some way ? yes. This can be done easily with a tool since you can dump a map content from HAProxy's socket.
