While work on a Magento website, you may encounter many common errors, but this is one of the rarest errors. Only a few users come across this. This warning relates to the total number of database requests a site can make when it’s running on a shared web hosting.

Most of the small websites are using shared hosting, and servers have the limited resources. Error while sending a QUERY packet means the server is not ready to send any further database request. It means your website will remain as it is. Therefore, whenever you update a blog post, publish it, integrate a module, install a theme, you will encounter this warning. It means whatever is related to the database, it will stop.

Start With the Database Optimization

As we have mentioned above, this error relates to the number of database requests. And you should know that every web hosting has its limitation to those. Some firms use the limitation to the total number of database requests per hour whereas others calculate it in a day. In either case, if the numbers of requests have exceeded by its limit, no further requests are processed, and you face with such troubles. Also, it disrupt the design of your online store. So, you need to optimize the database. As you know that, when you edit a post, update it, publish it, integrate a module, install a theme or something similar, a new database table gets added to the database. As a result, the size of the database gets increased. Therefore, you need tp perform some tasks including:

  • Delete the draft database tables
  • Clear the deleted posts from the database
  • Delete revisions
  • Delete spam comments
  • Delete duplicate comments meta
  • Delete duplicate post meta

Enable a CDN

A CDN supports you enhance the website performance by generating a static version of your Magento website so that a returning user don’t use all the resources of your site again and the CDN shows the website. And of course, a CDN also acts like a firewall between your website’s server and the browser of the user so it’s good to have.

Besides, it helps to decrease the number of requests your website is making right now. When a visitor types the URL of your site and opens it, the HTTP requests are done and a CDN solve them pretty well. Whereas on the other side, if you don’t have it, the web hosting server feel a kind of a burden because it may not be capable of handling so many requests at one time. And at such time, you’ll get an error. A CDN may support you to solve this error.

Switch to a Managed or a Cloud Hosting

When your business online gets bigger, it needs more resources, and it makes more database requests. To solve those requests, a better server is a perfect solution. Moreover, you can switch to a managed hosting which is not so expensive as compared to a Cloud hosting. It’s crucial for you to know the total number of database requests your current web hosting enables your site to make per hour. Let’s say your website makes 9,00,000 database requests per hour. It might be too much to solve a shared web hosting. Even for their highest hosting plan. So only a managed hosting or a cloud hosting can meet so many requests
