How many connections do you have at the time? Do you have anything in your LTM log that looks suspicious? Have you done any packet captures using TCPDUMP? You will have to narrow down where the connection is failing. i.e. client to LTM or LTM to server. TCPDUMP can help with that.

I did a packet capture at both end ( Source and destination ) of the LB, but i do not see any abnormalities. A perfect 3 way hadshake, Completed SSL handhsake and then data transfer. Only suspect i can get is, a bunch of TCP retransmission packet from Source machine. connection at LB is very much minimal compare to its maximum limit.
