A fast processor, SCSI disk subsystem, and an optimized MTA like Postfix 
can help out with large lists.  Folks have reported lists as high as 
200,000 email addresses without problems.

You might want to check your lockfiles in ~mailman/locks
If there are files in there, then Mailman may think that some other process 
is using the database, and is locking you out.  The name of the lock file 
will contain the name of the mailing list and end in the process number 
that has the lock.

Assuming you find a lock file keeping you out, you can find the process by
ps ax |grep process#  (at least in Linux)

If the process is non-existent, then delete the lock file.  If the process
is frozen, kill the process first, then remove the lock file.  If its still 
running, then you've got to speed up your system!

Good Luck - Jon Carnes
