That's been a message that will pop up sometimes. Are you asking a question about it? It may be more helpful to post your question in the macOS forum: https://forums.macrumors.com/categories/macos.182/

Yes, I would like to know how to fix this issue, as it occurs every time facebook has been open for awhile. I will go to the link you provided and pose my question there. Thank you, Namara.
