[Mailman-Users] Large List Problem on Admin Screen

[Dean Richard Benson]

Using V2 of mailman, I am having a problem
whereby I create a list, populate the list
with 30,000 members (existing from another
system) using the add_members command.

That bit works fine.  I can go into the 
admin interface and see that everything
is setup correctly.  (its an announcement
only list btw).

When I try to post a newsletter to the list
it seems to be fine.  Except it _doesn't_
get sent and then when I try to access any
of the admin area for that list, the browser
hangs.  Also a number of lock files are 
generated and the CPU increases for around
10 minutes.  No matter what I do after this
I cant access the admin area.

Any ideas?

Thx.
