I also saw this message today when trying to run the Recompile HAL Files maintenance, when a report was running. It didn't log me out, but I had to wait until the report had finished before it let me recompile.
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...
