I ran into live queries issues after 4.2.2 update.
When I try to make requests in UI fleet, they hang for a long time and the result does not appear ( With fleetctl, requests are executed every other time).
I have similar issues after update to 3.12
P.S. the results of all queries from packs are executed and accepted on the server in the file osquery_results. And then they are loaded into Elastic. I have only problems with live queries from fleet UI and fleetctl.
