[Mailman-Users] invites for large user list fails

[Anne Ramey]

Is there a known problem with inviting relatively large groups of 
addresses at once, ex. 6K at a time?  I usually just subscribe, so I 
haven't run into this before, but I have a list owner who gets an error 
when trying to subscribe a list of 6000 addresses, but I've been 
breaking it up to smaller groups (<400) and they seem to work fine.  But 
when I get up to 1000+ it fails.

If we try to invite the whole list we get:


  Server error!

The server encountered an internal error and was unable to complete your 
request.

Error message:
Premature end of script headers: admin

If you think this is a server error, please contact the webmaster

This error didn't really tell me what was wrong, but I guess I'm just 
not reading it right.  This was the only thing I could find that seemed 
to be an error:
TypeError: unsubscriptable object
Does this mean there was just one address on the list that freaked it 
out? f it is one email address, how do I tell which one?  They all look 
OK to me when I scroll through.

Help?
