A server process can become a 'zombie' and hold open network connections. These zombie connections block new requests, making the server slow. The server will not show error messages.

A server process can become a 'zombie' and hold open network connections.
These zombie connections block new requests, making the server slow. The server will not show error messages.
A 'zombie' process is an old program that is still running. It holds open network connections. These connections are called 'keep-alive' connections. New requests must wait behind these old, unused connections. This makes the server slow.
A developer restarts a web server. The old server process does not shut down completely. It becomes a zombie process. New users try to access the website. Their requests are slow because the zombie process holds many connections open. The developer checks the server logs, but there are no error messages.

Before starting a server, a developer must kill all existing instances. After killing, the developer must check that no instances are running.
A developer must always restart the server after any file change. The developer should never tell a user to run the server.
When an AI model starts a program, the new program is linked to the AI model's process. If the AI model's process closes, the program it started will also close.
A developer uses multiple servers for different parts of an application. Each server has a specific job.
