Package: isc-dhcp-server
Version: 4.1.1-P1-11
Severity: normal
Problem is caused by the use of 'option slp-directory-agent' and/or 'option
slp-service-scope'. By removing these, dhcpd loads up normally:
berk:/home/alex# tail /var/tmp/dhcp-ldap-startup.log
}
}
}
shared-network "lar-1" {
option domain-name "soas.ac.uk";
option domain-name-servers 193.63.73.32;
option domain-search "soas.ac.uk";
option wpad "http://proxy.soas.ac.uk/";;
option slp-directory-agent true 212.219.139.134;
option slp-service-scope true "SOAS_SCOPE";
<------- 100% CPU SPIN HANG

Although I am using the LDAP functionality, it's repeated with the non-LDAP
enabled dhcpcd. This seems to be an upstream bug and linked to the parsing of
that option, attached is a backtrace of where it is looping:
