I've noticed that there is built-in "Detect Discovery Servers" server task which runs every 10 minutes.
Description says "Detects newly installed discovery servers and enabled them to run discovery scans", but I'm not sure whether I really need this task and what this task is actually doing?
I'm running ePolicyOrchestrator 5.3.1 with DLP 9.4.100
It gets added with DLP/ Device control 9.4 by default. You can just disable it if you don't have DLP Discover licenses/software installed in your environment.
