There is a frequent disconnection of site probe from OPMC.This gets reconnected once the services are rebooted always.Tried the IntDB from the path C:\ManageEngine\OpManagerProbe\pgsql\scripts but still the same.

Enclosing the Screenshot for your understanding as well.

 There are no errors in the EV of server or OPMC which states any connectivity or issues at the other end or server's perspective.
