hmmm, this has been an issue for us but we understood that this happens as a result of the single stream..."idle tasks"...we will look this up..seems to be some worth knowing about. Thanks for the hint Jarek!!
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...
