Hello, I recently upgraded from HAProxy 1.5.4 to HAProxy 1.5.11, which included an upgrade from OpenSSL 1.0.1i to 1.0.2a, and my load balancers have since been crashing 1-2 times a day. I was able to follow the steps outlined here ( http://permalink.gmane.org/gmane.comp.web.haproxy/7992 ) and get a dump:
