 I am running the following setup:
 - Kea (DHCPv4) installed on Debian 7 with a single pool configured
 - perfdhcp installed on the Debian 6 system directly connected to the
 server system
 - Memfile backend is used to handle lease assignments

 Server starts successfully. I start perfdhcp on the client machine:

 {{{
 ./perfdhcp -4 -R 65535 -r 10 -n 100 172.16.1.1
 }}}

 When perfdhcp is started, the server crashes immediately with the
 following error log:
 {{{

 Similar issue has been discovered a few months back when using MySQL
 backend. It has been reported and resolved as #2723.
