My WordPress installation was working quite well, however it recently stopped properly updating feeds when new posts are published. I may have deleted a tranistent feed table using the Clean Options WordPress plugin. I don't know if that's the cause, but I can force it to update by changing one of the Feed settings manually each time.

How can I get it working properly again?

Any suggestion would be appreciated.

Do you have some kind of caching enabled? – goldenapples Jan 9 '11 at 4:12
What feeds exactly you are referring to? – Rarst Jan 9 '11 at 14:39
It fails to update RSS2, RSS, Atom, and RDF feeds. Say I just post an article right now. The feed will only show the items from before then. Not the just-posted story. If I go tweak a feed setting, it then gets flushed and works. But I have to do that each time. I am using W3 Total Cache. – Sahas Katta Jan 9 '11 at 17:39

Do you refer to feed settings in WordPress or W3 Total Cache?

Since I think this is indeed likely to be caching issue I'd check following:

  1. Check that feed is not getting stuck in browser cache (force reload, clear cache and reload).
  2. Verify that headers on feed make sense, http://redbot.org/ is good tool.
  3. Try to disable feed caching in Performance > Page Cache and see if it makes a difference.
  4. Enable debug mode for page cache in Performance > General Settings and look through information it gives on feeds.

I was having the exact same problems and making sure that feeds weren't being cached in W3 Total Cache worked for me! Thanks so much for the help! – user3666 Mar 3 '11 at 8:57
