FastCGI process exceeded configured activity timeout
FastCGI is a protocol for interfacing interactive programs with a web server. The "activity timeout" refers to the amount of time that the web server will wait for a response from the FastCGI process before considering it to be unresponsive and terminating it.
If the FastCGI process takes longer than the configured timeout to respond, the web server will generate an error message like "FastCGI process exceeded configured activity timeout" and terminate the process.
For example, if the activity timeout is set to 30 seconds, and a FastCGI process takes longer than 30 seconds to respond to a request, the web server will terminate the process and return an error message to the client.
This error message can occur for a number of reasons, such as the FastCGI process being stuck in an infinite loop, a slow or overloaded database, or a heavy computation.
To fix this issue, you can increase the timeout setting, or try to optimize the code of your script, make sure that your dependencies are up to date, or optimizing the database query.
