Dear Maintainer,
there are some points of reported problem:

- DHCP server is used like secondary server for failover high avalability service
- problem with 100% CPU consuming
- service was troubleshooted with commands: strace dhcpd -f

Problem output:

read(8, "", 4047)                       = 0
gettimeofday({1363957696, 815455}, NULL) = 0
select(22, [4 5 7 8 9], [], NULL, {13, 422598}) = 1 (in [8], left {13, 422596})
gettimeofday({1363957696, 815495}, NULL) = 0
gettimeofday({1363957696, 815511}, NULL) = 0
