Understood! My reply was related to message only, as I was afraid he might have mistook the problem description. Hence, I wanted to clarify this. I have taken your advice to upgrade to OpenSSL 1.1.0 seriously and did accordingly. We are now using OpenSSL 1.1.0g and everything seems to be doing fine so far. This matter can thus be regarded as solved. Thanks to everyone who contributed!
