dhcpd on 9.0_STABLE amd64

[Uwe Klaus <uklaus%hgb-leipzig.de@localhost>]

I am using the built-in dhcpd daemon with a GENERIC kernel on 9.0_STABLE 
amd64.
On several vacations am seeing messages like this

Jun 29 09:56:19 hgb1 dhcpd[319]: Null pointer in option_cache_dereference: 
/usr/src/external/mpl/dhcp/bin/server/../../dist/server/dhcp.c(3994)
Jun 29 09:55:51 hgb1 dhcpd[319]: Null pointer in option_cache_dereference: 
/usr/src/external/mpl/dhcp/lib/common/../../dist/common/options.c(4042)

Afterwards the dhcpd daemon gets unresponsible and needs to be restarted.

Any recomendation to track down, or should I try pkgsrc isc-dhcpd4.


Best regards,
Uwe
