My ESA working, but on the tab Alert -> Summary I see error messge "Error getting data". Somebody had same issue? ESA is 10.4.0.2.1486-5.
yes I have seen it. It may have something to do with the services crashing.
I had the issue because of the migration of alerts, maybe you should take to support services.
It's not a trivial matter.
