Hi, Thanks for the post. There has been issue fix and optimization with respect to large number of events (alerts) as a part of OME 2.0.1 release. Please try upgrading to OME 2.0.1. It should fix your problem. Do not forget to take a backup of the database before you initiate the upgrade task.
Good Day, When our said existing OME event table hits approximate 20,000 records, OME will fail to load the dashboard when launched (the black "OpenManage Essentials" box just sits in a loop and the dashboard never appears). The release notes for 2.0.1 don't seem to indicate a fix; can the OME team please confirm this and, if so, provide an ETA for a resolution? For your reference, the original ticket number for this issue is: SR #897481805 Thanks, Chad Warden Metro Vancouver IT   
Issue in OME 1.3.0.1533; will 2.01 resolve it?
