Hi All,
Sorry for delayed response, thank you all for responding to my query.
1) We are using non-blocking sockets on RHEL 7.0 machine with the kernel version 3.10.
2) When we run client and server in the same machine it works fine. Client and server able to exchange the data without any issues. But if we run client and server in different machines, we face this problem.
Server side logs when we run the server and client in same machine
Client side log when we run the server and client in the same machine.
3) as suggested by Matt i disable the client auth when client-server run in different machines and surprisingly the TLS negotiation is successful. That leads me to suspect on segmentation and reassembly.
Server side logs when the client auth is disabled
Client side logs when the client auth is disabled.
I took a wireshark trace and found that the server is able to receive the client certificate in 3 fragments and responding with the proper sack with right TSN. But server do not respond with its own certificate after that. I have attached the wireshark trace for the same. Path MTU in both the systems set to 1500.
I took the strace of the calls between server and client but i could not figure out anything with the strace. I have attached the same in the mail. strace summary table is as below.

I am new to openssl code could not figure out how to debug the issue at socket layer. Can some one help me to understand how to go forward to resolve this issue ?
Thanks and Regards,

Certificate messages. Obviously the client is able to read them just
fine (because it responds with its own Certificate message), but there
could plausibly be an issue on the server side. It would be interesting
to see what happens if you temporarily disable client auth so that the
client does not send this large Certficate message.
