My System Keychain seems to have issues. It occasionally (about once every two days) asks for my System keychain. So, I type in my admin password and it fails. I click Cancel, open Keychain Utility proper, and click the unlock icon. Type in my password (same one) and like magic it works.
This was pre-10.4.3 BTW. My login keychain is fine.
