           Summary: DHCPd doesn't start with slp-service-scope option
                    (infinite loop)
    Classification: openSUSE
           Product: openSUSE 11.3

I'm using the official OpenSuse 11.3 ISC DHCP version 4.1.1.P1 package but have
some issues with it. The DHCP server itself works by-design with about 2700
subnet declarations, Dynamic DNS with TSIG, several custom DHCP options etc,
etc (manual configuration, no Yast). But the same behaviour is seen after clean
package install with basic configuration.

The moment I add a single SLP Service Scope DHCP option the DHCP service fails
to start. It doesn't matter where, global or subnet section, I configure this
option the results are the same: 

After starting the DHCP server the init script "hangs" infinite while the CPU
is running at 100%. When I _remove_ this SLP option from the dhcp configuration
the server functions correctly again. 

This only occurs with the slp-service-scope option:

option slp-service-scope true "SLP-SCOPE";

The directory-agent option has NO issues:

option slp-directory-agent true 1.2.3.4 5.6.7.8;

Reproducible: Always

Steps to Reproduce:
1. Add dhcp option to /etc/dhcpd.conf : option slp-service-scope true
"SLP-SCOPE";
2. Restart dhcpd
3. Wait endlessly 
Actual Results:  
ncs-02:~ # /etc/init.d/dhcpd start
Starting ISC DHCPv4 4.x Server

(...Endless Wait...)

Expected Results:  
ncs-02:~ # /etc/init.d/dhcpd start
Starting ISC DHCPv4 4.x Server [chroot]                                        
                                                         done
