Yes. This is a serious bug which basically makes M/MX routers unusable if you want to have DHCP relay agent functionality *on the router* at the same time as you have other DHCP unicast traffic (for instance generated by a Cisco CPE with "ip helper", or a client sending its renewal request directly to the DHCP server) passing *through* the router. I find it absolutely incredible that Juniper with its ERX history has managed to botch the M/MX DHCP functionality this badly. Verified with 9.5R4.3 and 10.0R2.10.
