Welcome to the club, we seen this on every vSphere+EQL solution we deployed over the years. Most customer dont see it because the havent configurated the special Alarm notification on vCenter. The "problem" occurs once a week or month. Most of the time not all of the datastores are effected and also not every Host. The reconnect is done in the same second and we never see greater problem there. The bad this is that you get the false-positive alarm mails. Regards, Joerg
