https://lists.launchpad.net/openstack/ out of date (since May 2nd)

I can see that several list archives have no email after 2011-05-02. I think mailman is stuck. A restart my remind it to clear the queues.

I believe one list received several hundred messages on May 2nd (ubuntu-x-swat), and its archive is too large to process quickly. I think this caused a backlog of several thousand messages in the archive queue. We can see for example that there were 5 messages queue to be emailed, but there were 5000 messages queue for archiving. We can also see that messages are now clearing the archive queue in seconds. We think backlog will clear this weekend.

If the backlog is still present after the weekend, we need to investigate how to purge the queue or block large lists from being archived.

Looks like it finally caught up...

Thanks Curtis Hovey, that solved my question.
