[Star Wars] Why did Palpatine tell Vader to stop hunting Obi Wan?

The Emperor spends so much resources and time trying to hunt down and wipe out the survivors of Order 66, then Vader finally finds and confirms that Obi Wan is alive and strong enough to still kick his ass and when he reports to the Emperor Palpatine just tells him to stop worrying about it, calling it a distraction. Shouldn't Palpatine want one of the highest ranking Jedi dead?

It's possible that he's worried that Obi-Wan will be Vader's downfall, in one way or another. As you say, Kenobi kicked Vader's ass. Whereas evidence suggests that, left alone, Kenobi will stay out of the way of the Empire. So what's the benefit of sending Vader out to find him again, as opposed to the many other things he could be doing?
