`root@birds:~/tmp/nginx# ./objs/nginx -t -c ../nginx-ssl-fingerprint/nginx.conf

i did not test if your patch is causing it or the nginx version your patch is made for (in the guide you clone an specific version of openssl and nginx) ,even if it's the latter we should change the nginx version so i though i must report this

my os:

I believe that the "memory leaking" is related with nginx.conf parsing, so it should only happen once and can be ignored. In our production, this module has not been observed a real memory leaking.
