Interference between multiple DHCP instances on the same server

I have installed additional DHCP instance on the same physical machine
(different interface) that has another DHCP.
I’m binding each server with the interface at the startup: dhcpd
<options> <interface>
On the other hand, I’m noticing strange behavior:

The second server is receiving the request from the correct interface
but the response is sent from the other interface. I checked this by
‘snoop’ the two interfaces. I tried also compiling the server
(solaris) with USE_SOCKETS support (even though it is designed for
another purpose) and define local-address / server-identifier without

Any hint where could be the problem.
