Hello: But, can these cause the server to eventually stop responding? POP and IMAP connections are no longer possible, and after a restart it comes back. So the next question is, should I consider an upgrade, and if so, what steps should I consider? What should I backup prior to installing? Am I able to use the rpm?

A: Nothing is wrong. These messages are logged whenever Berkeley db encounters lock contention, but isn't necessarily a problem by themselves. This is especially likely when you have an empty or small duplicate delivery database and are receiving a large volume of e-mail. Berkeley db 4.0 has a bug where the number of lockers isn't decremented properly, causing this number to be unreliable.
