I've noticed how inserting characters like «-» in a virtual server name breaks the regex match on the output of «relayctl show redirects».
The aforementioned regex match is in the file /usr/local/www/status_lb_vs.php, inside the parse_redirects function

[...]
      $regs = array();
      if($x = preg_match("/^[0-9]+\s+redirect\s+([0-9a-zA-Z\.]+)\s+([a-z]+)/", $line, $regs)) {
        $vs[trim($regs[1])] = array();
[...]

It appears as though only the set of alphanumeric characters plus «.» is allowed, however the virtual server creation form validates names with additional characters, such as «-» above.

The result is a virtual server displaying an "unknown state", regardless of its actual condition.
