[Interest] QTimer stops triggering

[Vannoote, Frederik]

Hi Syam,

 

 

 

The Qtimer object is only created once and lives on for ever.

It has an interval of 30 seconds.

 

Most of the times they stop triggering after 1 or 2 days.

 

 

 

 

Kind regards,

Frederik

Hey all,

 

 

 

I'm having a weird thing about Qtimer which I can't explain until now.

We are using a dedicated application to kick the processor watchdog.
This application is based on a QTimer. Basically, it only has to call an
ioctl once every 30 seconds. This is the only thing the application
does.

 

We see that after a random time, the QTimer stops triggering. We have
proven that it does not get stuck somewhere, it just does not get
scheduled any more.

I've replaced the code with a while loop instead of the QT event loop.
That seems to be running fine.


Do you mean to say that you have set the QTimer to have a time-out of 30
seconds?
And what is the order of time after which the timer seems to stop
working - minutes, hours?

Also, (a wild shot) are you by any chance creating the timer objects
afresh everytime?
