• DNN 7.4.2
• The instance is nearly 10 years old
• Nearly 1000 portals on one instance
• Azure-hosted
• Custom and third party modules installed
• Light Caching enabled

We have an ongoing caching problem where changes (new pages, page settings, module changes, module settings/permissions, admin settings, host settings, etc) take typically 24-48 hours before anyone sees the changes. This happens with native DNN modules and third party modules alike. We often have to Recycle Application Domain to clear everything out so everyone sees the same changes.

Any idea what might cause this problem?
