To create event, it is duplicated!

Hello,
it is from two days, my scheduler when I create event, it calls two time insert event!
I don’t understand why! Which function call insert?
Is it yet happened? Can someone help me?
Thanks

Is it possible that several instances of the dataprocessor is initialized in your code?

If so, that would explain duplicated updates. If it’s not the case - please provide some kind of demo so we could check the issue
