Comment 5 for bug 1520890

Please return this version:

# Check if server is running with jemalloc - if not warn that restart is needed
if [ $ENABLE = 1 ]; then
  printf "Checking if Percona Server is running with jemalloc enabled...\n"
  JEMALLOC_STATUS=$(grep -c jemalloc /proc/${PID_NUM}/environ)
  if [ $JEMALLOC_STATUS = 0 ]; then
    printf "ERROR: Percona Server is not running with jemalloc, please restart mysql service to enable it and then run this script...\n\n";
    exit 1
  else
    printf "INFO: Percona Server is running with jemalloc enabled.\n\n";
  fi
fi

I think all the changes need to be tested in docker before publishing.
Thanks
