221g blue slip with administrative processing - after 2 months 221g white slip asking for documentation

I received 221g blue slip at Chennai consulate after my H1b Interview on 24-Mar-2017. After waiting for 2 months again I received an email from consulate issuing 221g white slip asking for the documents which I already submitted during the interview. I forwarded the same email to employer to respond with the required documentation. Has anyone faced this issue? If so, what are the next steps taken by your employer? Please advice me.

I am also in same situation. Got any update with your case?
