php7 MongoDB waiting for replication timed out

Question

之前使用的是 PHP5， 用的 Mongo 扩展，升级到 PHP7 后，没有使用 MongoDB ,使用 jenssegers/mongodb 这个composer 包。

参考 升级PHP7操作MongoDB 这篇文章

public function update($where = [], $update = [], $upsert = false) {
        $this->bulk->update($where, ['$set' => $update], ['multi' => true, 'upsert' => $upsert]);
        $result = $this->mongodb->executeBulkWrite("$this->database.$this->collection", $this->bulk, $this->writeConcern);

        return $result->getModifiedCount();
    }

偶尔出现 MongoDB\Driver\Exception\BulkWriteException: waiting for replication timed out
