Hi,
We are running the ASA 5525, 9.4.2 with cluster(Master/Slave). we found that some of the voip subnet using phones are not getting the ip address from dhcp server
we did the debug on the firewall and found below errors. this issue is not constant for single vlans. it changes to different vlans.
ASA debug:
DHCPRA: relay binding created for client 00cc.fc4a.30d6.
DHCPRA: setting giaddr to 10.4.22.1.

I don't find any bug for this issue. but i found one bug but it is related to old version 8.4.3.
