Minor Description
Seems like memcached hangs when no password is passed in ifconfig command, while it needs a password for encrypted pkey.
How to reproduce:
1) Upload encrypted certs, use external script to extract password
2) Modify the script to return not zero status (add "exit 1")
3) Restart the server
4) Ns server tries to push TLS config without password to memcached and memcached gangs
