Comment 2 for bug 1439673

Confirmed with PXC 5.5.41 and 5.6.22. It seems, this issue is only with deb packages.

mysqld_status () {
    mysqld_pid=$(cat $pid_file 2>/dev/null)

    if [ ! $mysqld_pid ];then
        echo "MySQL PID not found, pid_file detected/guessed: $pid_file" | $ERR_LOGGER
        if [ "$1" = "check_dead" ]; then
            return 0
        fi
        return 1
    fi

    ping_alive=1
    ps_alive=0

    soutput=$(mysql -u root -pabcd -e 'select 1;' 2>&1 | grep 'ERROR 2002')
    [ "$soutput" ] && ping_alive=0
