what u used is not idle task , it is some import on startup
NewPeriodicTask should be used for example OnApplicationStartupComplete
and there are more things to consider there
and creating 20000 items will take time ......
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...
