I have deleted them on startup. It took almost one hour 17:04:21-17:59:54 at a rate of ~167 records per second.
I can see in the 2023-07-23 version it's probably fixed.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
