I am still waiting to get more information including tcpdump from the customer.

This email thread appears to be somewhat related, but I did not find any follow-up responses. 
Any comments on this?

    Yes, the same client connecting to the same server name/address both times within a few mins of each other.

    I will try to get tcpdump captures for both as well as DNS lookup times.

        DNS/naming resolution lookup times ? Are they connecting to
        exactly the same name ?
