[Mailman-Users] "Messages Awaiting Approval" email wildly inaccurate

One of our mailman lists sends a daily message saying that it has over 8,000 waiting messages in the queue. This number increases daily no matter what we do.

Trying to go to its moderation page results in a server error. The server error in question is the kind that generally requires the use of mailman/bin/discard in order to get rid of the messages.

Actually running mailman/bin/discard deletes only a few messages, and there are no remaining messages in mailman/data after this has been run. But the next day's "waiting messages" email increases, rather than decreasing or remaining constant.

I think this is the result of someone manually deleting messages from mailman/data.

Is there any way to fix the problem?

Thanks Christopher
