[Mailman-Users] Can't login mailman list admin web

[Stanley Chen]

We have a list running 30,000+ list members.

Recently we have sent out several mails to this list, and it's still 
running.

However, we can't login to the admin webpage. After we input password, 
the page was loading as shown in the status bar, but after several 
minutes still can't show the admin page and finally it said "page can't 
be loaded".

How can we solve it?
