The resolution state of 202 is used to indicate that an event that needs to be processed by the Smarts OpsMgr Adapter. To address this issue, do the following:
select count(*) from alert where resolutionstate = 202
Update Alert Set ResolutionState = 0 Where ResolutionState = 202
By resetting the value to 0 (unprocessed events), the connector can then successfully initialize and process the events.
