Bringing sync gateway database online taking infinite time

I have taken a sync gateway offline because one database was not responding. So I made the database offline on one sync gateway in the cluster. The offline worked very fast but now when I am trying to bring the database online its not working and taking a very long time. Right now it has been above one hour. Please note that while taking it offline I did not send any thing in the post body.

The access to server where the sync gateway is installed is not available. Please help in urgency.

@pankaj.sharma,

It should boot strap very quickly.
What do the SG’s log say when you start SG?
