Comment 6 for bug 2031482

It happened again, so here is some more context. DHCP leases on the subnet in question are set to 1 hour.

2023-09-06 AWST

11:39:39 We restarted maas-rackd daemon on the 2nd (acacia) rackd server
13:17:21 DHCP leases started to drop and we went about discovering the problem
13:45 We set subnet 63 from fabric 0 back to fabric 55 where it was before
13:47:41 DHCP leases began to be reissued

Here are the logs. I trimmed syslog a little to only show more recent entries.

Remember that nimbus rackd1 logs are in UTC, while the others are in AWST UTC+8.
