You need to  GET/PUT (Update) the list header for LISTSERV to re-build the
indices.

No. You must do the above, but this will happen at midnight if you don't.

>Does the Listserv server need to be restarted?

No if you do as above. It's not recommend you edit the current notebook.
If you do it will throw the current Digest out of sync and your list will
be HELD indefinitely. You must either send the digest or delete it before
editing. Then make sure no new messages are processed until you are done.
HOLDing your list while editing is the best thing to do, (after
sending/deleting the Digest).
