Hello All, We are facing this issue for quite sometime, a random crash in SSL3_accept. We yet to figure out the exact cause as it's quite random and does not happen frequently - but it does happen once in a few hundred thousand connections and crashing the server. We are using openssl 1.0.1e on CentOS 7.2. I hope to get some help here, will be happy to provide additional information if requires.
