I have started encountering very weird behavior...

    - My message are files by procmail to ~/Mail/spool
    - When I request new files for group, Gnus read the spool
      file and I can see it storing the messages to nnml group
    - The count of new messages is correctly updated to Group line
    
    So far so god, but when I enter the Group, The summary buffer
    doesn't contain the new articles, while they are in the directory
    if I list then.

    If I exit the group, the Group line now say 0 new messages,
    while I did nonthing? The new messages aren't seen by Gnus any more.

    Does this have anything to do (side effect?) with the command M-x
    nnml-generate-nov-databases. I notice that the article numbers
    don't continue any more, but are somehow wrapped to lowest values.
    Does that indicate anything?
