This issue, I'm facing for openssl-1.0.2e/g/h version.

Run openssl server: Used 16K Certificate and Key
./openssl s_server -cert sercert16384.pem -key server16384

Run openssl client:
./openssl s_client -connect <server_ip>:port_number -cipher AES128-SHA -tls1


139812135450280:error:1408E098:SSL routines:ssl3_get_message:excessive message size:s3_both.c:417:

This error is coming while using AES128-SHA as a cipher and tls1/1_1/1_2 protocols. It's working fine with ssl3 protocol.

1. This issue, I didn't face for the openssl-1.0.1p/e version.

Can you please confirm. is this known issue?
if it is the known issue. Can you please share that fix?
