Stack overflow – site unusable

    Hello

    I’m using version 2.4.11.1. I have redis object cache enabled.

    After some time, my website becomes unusable. Clearing the object cache usually does the trick, but it has become a real problem.

    Here’s the PHP stack trace. It becomes an infinite loop between set_status_data() and get_app_config(). Looking at the code, it’s pretty clear it’s bound to happen when the condition “// old status format?” is true.

    Code fix would be very much appreciated. Thanks.
