QuestionActive PID Pin

I had to write an application long time ago whose job was to check if PID is Active or not.

The Scenario was:
Crontab will execute a process every minute
Process takes longer than a minute
So, new process will check if PID file exists or not
If PID exists new process will abort.
But before aborting new process will ensure that current process is not running longer than 30 minutes. Because, it is observed if the particular process is running more than 20 minutes, it's because some exception that the process couldn't handle. In this case, we simply kill the process for greater good.

Then a scenario crossed my mind.
What if somehow current process failed remove the pid file(whatever the reason) and the PID I am trying to kill is not my my process.

What is the possibility of reaching this scenario.

FYI, I don't handle that service more than 2 years, it's still running. But I want to know if there is any issue.
I do not fear of failure. I fear of giving up out of frustration.
