There seems to be a change in behavior after all. There is a new message 
in the syslog.

Feb  5 07:02:09 6bone dhcpd[3152]: Null pointer in 
option_cache_dereference: /usr/src/external/mpl/dhcp/bin/server/../../dist/server/dhcpv6.c(1980)
Feb  5 07:02:49 6bone syslogd[813]: last message repeated 260862 times
Feb  5 07:04:49 6bone syslogd[813]: last message repeated 890730 times

The dhcp process runs with a high CPU load and generates the messages.
