Hello.
I have redundant 5506x and frequently the FW will not hand out an address to either a PC or phone. If a forced failover or power cycle occurs, it fixes the issue until it occurs again. This configuration has been working for years. Inside interface is configured with 3 sub-interfaces and DHCP is configured to only hand out address for the inside LAN. Lease time is 1 week. Stats and Binding show no errors or the lack of IP's available.
Thanks in advance for any ideas.

can you post the ASA code running and some config snippets ? is the ASA acting as DHCP Server ?

This sounds very buggy. What version ASA are you running? If you are running a slightly older version it might be an idea to upgrade to the latest "star" release.

dhcpd auto_config outside
are you use asa as dhcp client, i.e. config DHCP in OUT interface?
as I know the ASA failover not support DHCP client, it support DHCP server and DHCP relay.
