For resolving this issue, there is something called as READ_COMMITTED_SNAPSHOT which is by default OFF and it should be set to ON. The below SQL command can be used to update the property.

SELECT is_read_committed_snapshot_on from sys.databases where name=’infarep’ — This should be 1, which is equal to ON
