We noticed the crash on high traffic servers with a high SSL connection creation/destruction rate. Today we got some DoS like traffic on some instances and they crash almost immediately after restart. I realized that the application was deploying multiple verticles. Once we switch to a single verticle per process the JVM no longer crashes. Another way to prevent the crash is to use JdkSSLEngineOptions instead of OpenSSLEngineOptions.
