Need to restart computer with webapp to see changes

Hi Folks,
recently, I made a very small modification to a web app on a mac mini
I only changes a line in a constant, re-build, copy to the server and run the app with terminal.

the new value of the constant was the old one !
I had to restart the mac mini, re-launch the web app and this time it was the good value.

is it normal behavior ? is it something in the caches ?
the constant was the content of an email sent bt the web app. the email has been sent but with the old value…

Apache?

Did you kill the running app first?

I presses ctrl-c in the terminal window. and got the prompt. is it enough to kill the app ?

I know there was previous bug fix:

Fixed a regression which made it so you couldn’t stop a web app that was run from a console window using CTRL-C on macOS and Linux.

So it’s possible this wasn’t 100% fixed or has returned. You might want to check and see if the process is still running after you hit ctrl-c…

No, just a fresh macos 10.13 and the web app run from the terminal.

when you press ctrl-c check to see if the process is still running with ps or Activity Monitor.
