The telemetry1000 is our Product Improvement Program for McAfee Agent 4.8+ which sends anonymous data back to McAfee so for some reason it's not working correctly on that system or however many systems are sending the event. It won't cause any product functionality issues but if all of your systems are getting the error then you might as well uninstall it from your environment.
you can manage this with EPO.
Under the EPO Server settings Product Improvement Program can be enabled or disabled. There is also a link available to the McAfee website how this software can be removed from the endpoint.
