after 9 server, last server_id=9, the 10^ started by 0...strange: Code: $conf['dbmaster_user'] = 'ispcsrv0'; were you able to add more than 9 server? i searching into lib/installer_base.lib.php (php) class installer_base and line 292 is very strange Code: $conf['server_id'] = $conf['server_id'];
The number of slaves is not limited. I guess the reason for this username 'ispcsrv0' is that the insert of the server record on the master server failed and mysql returned a auto increment ID 0 in that case. 1) Check that you really used the mysql root user of the master server to install ispconfig. 2) Check that the "server" table is not crashed, e.g. by running a mysql repair on that table with phpmyadmin. This line does exactly nothing. Its not required but it does not harm.
