Why does Remi restart the app at seemingly random intervals?

[johnperry-math]

At first I thought it was something I had done, but I added a print("initing") to MyApp's __init__ method in widgets_overview_app.py and sure enough:

$ python widgets_overview_app.py 
remi.server      INFO     Started httpserver http://0.0.0.0:8081/
initing
remi.request     INFO     built UI (path=/)

remi.server.ws   DEBUG    send_message: 1140264874... -> ('127.0.0.1', 50060)

I have yet to detect a rhyme or reason to it, but it causes serious problems in my program, which displays an image, which means it reloads it every time the the app restarts, which means associated data (dimensions, saved parameters, etc.) get reloaded, and that's breaking things left and right.

Why does this happen, and is there a way to prevent it?

I'd advise to check the browsers console, it could be your browser invalidating something and forcing a refresh. Or at least you may find some additional logs that help debug the issue.
