      ========================================
      Gitea Configuration Update Complete
      ========================================
      Gitea configuration has been updated successfully!
      
      Changes applied:
      - Redis cache enabled (persistent, survives container restarts)
      - Redis sessions enabled (better performance and scalability)
      - Redis queue enabled (persistent job processing)
      - Database connection pooling configured
      - Connection limits set to prevent "Connection reset by peer" errors
      
      Gitea should now be more stable and perform better with Redis.
      ========================================
