Weird problem of multiple dhcp processes running in parallel!

Hi Friends,


I am facing a weird problem with the multiple dhcp process running in parallel.


My dhcp server was configured to listen on only one eth0  and there used to be only one process running always.

But because of some inconsistent behaviour in hosts not getting IPs, when observed the linux machine with the dhcp server installed, I observed 5 dhcp process running in parallel.

DHCPv4 server running in my linux machine.


dhcpd     1934  1.2  0.2  34844  8744 ?        Ss   16:25   4:59 /usr/sbin/dhcpd -4 -cf /etc/dhcpd.conf -pf /var/run/dhcpd.pid -chroot /var/lib/dhcp -lf /db/dhcpd.leases -user dhcpd -group nogroup eth0
dhcpd    19095  1.2  0.2  34972  8756 ?        Ss   Nov09  26:12 /usr/sbin/dhcpd -4 -cf /etc/dhcpd.conf -pf /var/run/dhcpd.pid -chroot /var/lib/dhcp -lf /db/dhcpd.leases -user dhcpd -group nogroup eth0
dhcpd    19349  1.2  0.2  34840  8728 ?        Ss   Nov09  26:01 /usr/sbin/dhcpd -4 -cf /etc/dhcpd.conf -pf /var/run/dhcpd.pid -chroot /var/lib/dhcp -lf /db/dhcpd.leases -user dhcpd -group nogroup eth0
dhcpd    20649  1.1  0.2  34840  8728 ?        Ss   Nov09  24:41 /usr/sbin/dhcpd -4 -cf /etc/dhcpd.conf -pf /var/run/dhcpd.pid -chroot /var/lib/dhcp -lf /db/dhcpd.leases -user dhcpd -group nogroup eth0
dhcpd    21533  1.1  0.2  34840  8736 ?        Ss   Nov09  24:07 /usr/sbin/dhcpd -4 -cf /etc/dhcpd.conf -pf /var/run/dhcpd.pid -chroot /var/lib/dhcp -lf /db/dhcpd.leases -user dhcpd -group nogroup eth0

May I know in what scenario multiple dhcp processes will be created?
