Thanks to all for the various replies. We checked for only one copy of Sendmail running, which is true. We also checked the logs, and, as you say, there was no indication of trouble. We adjusted run_queue and cron to process the queue every five minutes. This seems to have improved the situation, but not solved it entirely.
Every day we get a few complaints of multiple copies. The list is 30K subs. One person send both copies and they were about a half hour apart, which baffles me completely. One clue - at that time run_queue was running every half hour, and the queue was heavily loaded.
We are using a machine that only runs mailman for us, Linux version something very recent, Mailman 1.0.
Any further suggestions would be very much appreciated.

Some of our subscribers are reporting receiving 2, 3, or even 4 copies of each post.
I've seen very occasional examples of this on our list running mailman 1.0. The headers show that the duplication is occurring at the point where mailman injects the message into the MTA for delivery to the list subscribers.
I've just checked yesterdays logs and found one message that did this. In this case the final mail injection was duplicated - ie mailman injected the message 5 times to a different set of subscribers, and then injected it twice with the same recipient list each time.
There is no indication of problems in the mailman logs.
The injects were spread over a 5 or so minute period, with the last 2 (duplicated) injects done 2.5 minutes apart. The machine would have been quite heavily loaded around that time - there was a message still in the process of injection by mailman when the second arrived and a few messages in the mailq.
