What is the bug or the crash?

When running QGIS Server with QGIS_SERVER_PROJECT_CACHE_STRATEGY=periodic (see docs), QGIS Server should react on changes of the QGIS project. This works well for WFS but not for WMS.

Steps to reproduce the issue

• start QGIS Server 3.36 with this settings (Docker compose file as example)

version: '3.8'
services:
  qgis_server:
    image: camptocamp/qgis-server:3.36
    volumes:
      - ./pg_service.conf:/home/.pg_service.conf
    environment:
      - QGIS_SERVER_PROJECT_CACHE_STRATEGY=periodic
      - PGSERVICEFILE=/home/.pg_service.conf
    ports:
      - "8082:80"

• create a QGIS project with a vector layer named alpha and ensure it is published both as WMS and WFS
• store this project in PostGIS
• Make a WMS and a WFS capabilities request to the project in the database and remember the response
  • both responses should list the layer alpha in their response
• change the the name of the layer in your QGIS project from alpha to beta and save the project
• Request the WMS and the WFS capabilities again. Result:
  • WFS contains the layer called beta in its response
  • WMS still contains alpha in its response
