After extended periods of use, the website experiences frequent crashes

Currently, I am developing a website using a free provider (000webhost) and focusing on integrating a chat feature. To achieve this, I have implemented an interval every 500 milliseconds that reads a file to check for new messages. When a new message is detected, I load all the messages from a .txt file into an HTML element.

The chat functionality is almost complete; however, I am facing a challenge where my site crashes after extended periods of chatting or being on the chat page (approximately 3 minutes or more). Each time this occurs, I have to wait for about an hour before regaining access to the site. I use JavaScript and AJAX to refresh the chat every half-second.

Has anyone encountered a similar issue and could provide insight into what might be going wrong? I attempted to research the problem on Google but did not find any helpful solutions.

Edit: After adjusting the interval for refreshing the chat to 2.5 seconds, the website no longer crashed. It seems like this modification has resolved the issue.

Answer №1

It appears that the host has blocked your access, possibly due to too many requests being made in a short period of time. Making frequent requests from the same IP address can sometimes be mistaken for a denial-of-service attack.

There are more efficient ways to create a chat platform - consider using web sockets or node.js for better performance.

  • NodeJS Chat
  • Web Socket chat

Update

Tom mentioned in the comments that some free web hosts may not support setting up a Node server. In this case, you could try increasing the interval between requests or check with the host about any limitations they might have. Increasing the request interval may reduce the responsiveness of the chat, but it can be challenging to optimize everything on a free hosting platform.
