The modules list does not have too much traffic. It's very low traffic in fact. It has nothing to do with the volume of mail. When I look at the mail, it's specially tagged and highlighted for me for the requests that come in from the forms.
The thing that causes the problem is the PAUSE admins all being on vacation at the same time, or all being extemely busy at the same time. Usually that's not the case, but sometimes it all aligns. The admins also divide the work among themselves informally. I don't deal at all with new user stuff, and other people don't deal with new module stuff. Steffen is dealing with the database purging on his own, so he handles all of that. No one is contending with an overwhelming amount of mail to look through.
Normally I have a program that checks for unhandled requests. Around that time it broke because the latest versions of DBM::Deep aren't backwards compatible with the database format. I stopped using it for a bit around that time.
So, watch out before you start making assumptions about why things happened. We missed this one, but not because we can't handle ten messages a day. Be careful with your accusations: you're talking about real people.
