Dear QE users

I have a quick question:
I set
etot_conv_thr = 1.0E-9
forc_conv_thr = 1.0D-4 ,
in vc-relax procedure but the job ended when
 Total force =     0.016813     Total SCF correction =     0.000067

How is it possible? Do I have to add some other flags to reach smaller
forces?

Best regards,
Payam Norouzzadeh
