Closing now with commits on master—reopen with separate issues for OpenSSL 1.1.1/OpenSSL
Open a separate issue if your config actually manages to init OpenSSL in rank 0(thread#1)—this is the main cause of intermittent crashes. A possible example would be `db_mysql` with an SSL connection (I'm not able to test this yet). In the issue do list your config (list of all the modules and loading sequence).
