problem scheduler is creating Incident & Change Records :: How to troubleshoot?

 Hello Experts,

In our environment, suddenly since last 1 week, problem scheduler is creating Incident and Change records regularly at a particular timeframe. I have gone through Activity Log. Nothing much info is there. Gone through sm.log file as well. I haven't got anything over there as well.

Would you please let me know how to troubleshoot further if something is wrong in scheduler part?

I am not getting any hints where to start and how to go ahead to resolve the issue? Please let me know your valuable inputs regarding the same.
