My SSIS package has 4 data flow tasks extract data from Sybase to SQL Server. All 4 data flow task executes parallelly. However,
some times data flow task extracts only 1 record from source with no errors or warning message, though there are millions of records in source. But it happens only some time. When I executes data flow task one
by one with precedence constraint, it extract all the records with any issue. What could be the issue?
