Hi Lenin, the issue is probably that you don't have pound configured to choose which suites are used. At the moment, your server allows clients to choose, and they choose a CBC suite. I don't know how cipher suite preference is configured in pound, so I can't help there. You're looking for the equivalent of "SSLHonorCipherOrder On" in Apache httpd.
Hi Ivan Ristic,
Issue has been fixed. I got equivalent of "SSLHonorCipherOrder On" for pound which is "SSLHonorCipherOrder 1" for that i applied some patches in pound from http://jonaspasche.com/pound/
Thanks for your help
