please copy and post the original output of the commands you run, to
get the information about the used software versions, since no
"jack-audio-connection-kit-2.9999" does exists, as well as to post
the original error messages.

E.g run

  jackd --version

What is the output of

  grep memlock /etc/security/limits.conf


  grep memlock /etc/security/limits.d/*
