[SOLVED] Luci requiring constant re-logins

I'm not sure when this started, but I've just discovered that luci is requiring me to re-login every time that I change pages.

Any ideas where to look to figure out what is going on?

Reflash and re-configure.

Before you tear down everything:
a) make sure your browser accepts cookies
b) make sure you don't have a second browser tab open with LuCI

Browser definitely accepts cookies. I've restarted the browser and verified that the problem occurs with both Firefox and Google Chrome.

A reflash and re-configure shouldn't take more than 20 minutes.

Found the solution buried here. I had disabled rpcd as part of my cleanup/hardening.
