strange error during upgrade

hello

I am upgrading ispconfig from 3.0.5.3 to last stabel 3.0.5.4.p3
This is a multi-server
On main server cp, no error.
I am getting this error on all other servers

Code:

Starting incremental database update.

what is this "Duplicate entry '0-' for key 'serverdomain' "?
and
ERROR 1091 (42000) at line 1: Can't DROP 'serverdomain'; check that column/key exists


Edit:

here

Code:

grep -r serverdomain *
incremental/upd_0068.sql:ALTER TABLE  `web_domain` ADD UNIQUE  `serverdomain` (  `server_id` ,  `domain` );
incremental/upd_0078.sql:ALTER TABLE  `web_domain` DROP INDEX `serverdomain`, ADD UNIQUE  `serverdomain` (  `server_id` , `ip_address`, `domain` );
ispconfig3.sql:  UNIQUE KEY `serverdomain` (  `server_id` , `ip_address`,  `domain` )

 

I have a bunch of domains (webdomain) 10 domains, with serverid = 0 and domain name null, as you can see in snapshot
This is very strange as one cannot insert a new domain without entering the name in the form, and I have no script to create new domain by api (not yet...)
