Eu recebi apenas esses 2 erros ao converter arquivos simples em tabelas de banco de dados. O fluxo de dados parece funcionar para outros arquivos simples com o mesmo layout, então não entendo de onde esses erros podem vir.

[Flat File Source [204]] Error: An error occurred while skipping data rows.

[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED.  
The PrimeOutput method on Flat File Source returned error code 0xC0202091.  
The component returned a failure code when the pipeline engine called 
PrimeOutput(). The meaning of the failure code is defined by the component, 
but the error is fatal and the pipeline stopped executing.  There may be 
error messages posted before this with more information about the failure.
