Web page hangs if left running for a few hours

[andrewcliffoutlook]

When left running displaying a departure board for a number of hours with th e clock display enabled the web page hangs. I have confirmed the issue is something in the browser code. The apis on the server side are still responsive. If you refresh the browser screen it reloads the application and continuea working.

I have ensured there is nothing on the browser e.g. Plugins running that might be causing the issue.

Any thoughts how this might be solved?

Are you able to send over the URL your using as well as any changed settings, this will allow me to try and recreate the issue. You mentioned the clock, are you saying that if you turn off the clock then it doesn't hang?

Hi Ben,

I am Andrew's brother and we have been working on this issue together.

The URL's we have been trying are :
https://www.leddepartureboard.com/WOK/6?hideClock=false&hideMenu=true&showStationName=true
https://www.leddepartureboard.com/PBO/6?hideClock=false&hideMenu=true&showStationName=true

When we tried these URL's from our Browsers (Windows 11 - Edge, Chrome & Firefox) (Mac OS - Safari, Chrome, and Firefox) (Raspberry Pi 5 Debian 12 Bookworm - Chrome and Firefox) they all started 'pausing - clock stopped updating for long periods of time' after a few hours and eventually stopped all together (Clock stopped refreshing and departure boards were no longer updating).

We haven't tried it without the clock as we feel this is an important part of the leddepartureboard so that you can check the current time against the arrivals and departures.

We then tried running the departureboard in a Docker container on the Raspberry Pi 5 and running it through our browsers on Windows 11. Mac OS, Debian 12 Bookworm using the 'Localhost'
127.0.0.1/WOK/6?hideClock=false&hideMenu=true&showStationName=true

and using the actual local host IP Address

192.168.68.242/WOK/6?hideClock=false&hideMenu=true&showStationName=true

and still the same problems arose....clock pausing after a few hours and eventually the departure boards stopped updating and clock stopped all together.

When we opened 'Developer Tools' in the browsers we came across the same error each time....

'Uncaught (in promise) Error: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received'

I hope this helps

Kind regards

Steven Cliff
