QueueOverflowException - Item queue overflow. Check that the batch daemon is running

[Bilal Haidar]

Hi,

From time to time, we are having 500 error messages as shown below:

This is a PHP Laravel hosted on GCP App Engine Flex.

Any idea what's causing these errors?

Hello,

There is a likelihood that your response is larger than 32MB. As explained in this public documentation, "dynamic responses are limited to 32MB. If a script handler generates a response larger than this limit, the server sends back an empty response with a 500 Internal Server Error status code."

If this is not the case, I recommend to report the issue via the Public Issue Tracker or report it via your Premium Support Package so that we would be able to dig into the issue.
