[pkg-dhcp-devel] Bug#703698: isc-dhcp-server: 100% CPU consuming due problem with function gettimeofday

I believe this is a bug in the ISC dhcpd.  However, I did solve it in my 
case (Debian Wheezy isc-dhcp-server 4.2.2.dfsg.1-5+deb70u6).

netstat -pant|grep dhcp
revealed a lot of CLOSE_WAIT sockets to my DHCP server's failover 
partner (Ubuntu Trusty isc-dhcp-server 4.2.4-7ubuntu12).

It turned out that the secondary Ubuntu machine had two copies of dhcpd 
running (ps aux|grep dhcpd).  Killing the rogue version, and restarting 
the primary Debian version cleared up the issue.

But the dhcpd still treats CLOSE_WAIT sockets incorrectly....
