php - データベースでLaravel 5.2ジョブが詰まっていますか?

Question

ジョブで LARAVEL キューを使用してデータベースに大きな Excel を挿入していますが、いくつかのジョブが詰まって実行されていません。

ファイルの内容（ジョブごとに250行）をチャンクし、停止するまでほとんどの内容を挿入します。

コードの挿入 (250 行以下を挿入するジョブ)

public function handle()
{
    $uuid = Uuid::generate(4);
    $defaultsSize = 0;
    $customSize = 0;
    $defaultsIdFields = [];
    $customFields = [];
    if (sizeof($this->matrixDefaultFields) > 0) {
        $defaultsSize = sizeof($this->matrixDefaultFields[0][0]); //size of one of the vecs in default values
        $defaultsIdFields = $this->matrixDefaultFields[0][0]; // all default fields id
    }
    if (sizeof($this->matrixCustomFields) > 0) {
        $customSize = sizeof($this->matrixCustomFields[0][0]); //sizeof one of the vecs in custom values
        $customFields = $this->matrixCustomFields[0][0]; // all custom fields id
    }


    for ($i = 0; $i < sizeof($this->matrixContacts); $i++) {
        $contact = Contact::create(['UUID' => $uuid, 'id_contact_list' => $this->matrixContacts[$i][1],
            'nome' => $this->matrixContacts[$i][2], 'email' => $this->matrixContacts[$i][3], 'unsub_code' => $this->matrixContacts[$i][4]]);

        for ($j = 0; $j < $defaultsSize; $j++) {
            $defaultsValuesFields = $this->matrixDefaultFields[$i][1];  //field value
            CompanyListFieldValues::create(['company_id' => $this->idCompany,
                'contact_id' => $contact->id,
                'field_id' => $defaultsIdFields[$j],
                'isDefault' => 1,
                'value' => $defaultsValuesFields[$j]]);
        }

        for ($k = 0; $k < $customSize; $k++) {
            $customValuesFields = $this->matrixCustomFields[$i][1];  //field value
            CompanyListFieldValues::create(['company_id' => $this->idCompany,
                'contact_id' => $contact->id,
                'field_id' => $customFields[$k],
                'isDefault' => 0,
                'value' => $customValuesFields[$j]]);
        }

    }

}

ジョブのジェネレーターからのコード (これは正常に動作します)

      for ($row = $this->startFrom; $row <= $highestRow; $row++) {
        if ($rowMatrix == $chunksize) {
            // $job = (new importExcelInsert($matrixContacts, $matrixDefaultFields, $matrixCustomFields, $this->idCompany))->delay($jobDelay)->onQueue('excelInserts');
            //   var_dump($matrixContacts);
            $job = (new importExcelInsert($matrixContacts, $matrixDefaultFields, $matrixCustomFields, $this->idCompany, $rowMatrix))->delay($jobDelay)->onQueue('excelInserts');

            $this->dispatch($job);
            $njobs++;
            $matrixContacts = [];
            $matrixDefaultFields = [];
            $matrixCustomFields = [];
            $rowMatrix = 0;
        }
        $userEmail = $sheet->getCellByColumnAndRow($posEmail, $row)->getValue();

            $ignored++;
        } else {

                }

                $matrixDefaultFields[$rowMatrix][1] = $vecValues;
            }
            $i = 0;
            if (!$this->arrayCustomFields[0] == null) {
                for ($j = 0; $j < sizeof($this->arrayCustomFields); $j += 2) {

                }
                $matrixCustomFields[$rowMatrix][0] = $vecFieldId;
                $matrixCustomFields[$rowMatrix][1] = $vecValues;

            }
            $rowMatrix++;
        }
    }

    if (!empty($matrixContacts)) {
        $job = (new importExcelInsert($matrixContacts, $matrixDefaultFields, $matrixCustomFields, $this->idCompany, $rowMatrix + 1))->delay($jobDelay)->onQueue('excelInserts');
        $this->dispatch($job);
        $njobs++;
    }
