From boot, ipv6 leases are mostly assigned with leases of 1 hour. Occasionally leases of 14 days (as specified in Static Leases), and occasionally leases of 30 minutes and occasionally no leases (or leases expire and are not renewed).
What debugging / logging steps can I take to better pin down this issue?
I suspect that this is related to, or causes, occasional long stalls when opening new web pages, reported at [[https://forum.openwrt.org/t/frequent-stalls-on-21-02-rc3-possible-cause-is-dhcpv6/99761|the OpenWRT forum]]
In an initial effort to debug, I stopped odhcp and then started it on the command line with -l 7. The only logging that looked like a possible error are occasional sequences similar to this: odhcpd[8869]: Received 123 Bytes from fe80::215:5dff:fe01:aa0f%lan@br-lan

Is this issue still traced? I experience the same issue in OpenWRT 22.03.0 with a configuration in full accordance to the documentation provided. My sample configuration in /etc/config/dhcp, with emphasis on the relevant issue of lease time configuration, looks like this:
dnsmasq issues leases, which perfectly match the lease times defined in the relevant file. In contrast, odhcp only uses the lease time defined for the pool, in which the host defined in the specific host section resides.
If you need any additional input, please give me a hint.
