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.
I dont know what timer API is used by Qt. If its posix timers
underneath, Can you try a simple app with posix timers and see if they
also misbehave.
That way, we will know whether its a platform problem or qt problem.
Kind regards,

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?
