Upgrade to 24.1.2_1 "broke" WAN DHCPv6 client

[Ed V.]

Following update, I noted that the ISC DHCPv6 server was in "stopped" status and my ISP IPv6 assignment was empty /missing.

In the logs I see:

Code: [Select]

Error dhcp6c transmit failed: No buffer space available
after a reboot.

Running `dhcp6c` from command line also throws that error.

Code: [Select]

# dhcp6c -d -D -i -f igb1

Feb/22/2024 12:04:50: reset a timer on igb1, state=INIT, timeo=0, retrans=891

Feb/22/2024 12:04:51: set elapsed time (len 2)
Feb/22/2024 12:04:51: transmit failed: No buffer space available
I also note that checking updates, plugins, etc. goes into a "Waiting for another process..." state for 20+ minutes (and still counting) post upgrade - so "rollback" isn't yet possible...

Any hope?  Suggestions to "unstick" things?  Other data that would help debug?

+1, I do have the same behaviour with the exact same error. Only a reboot fixes the issue.
