This problem troubles us on occasion, today being one of those occasions. We are seeing this error message:
[Agent located at [WIN-KANQRBSIE3G, 10.132.44.244, C:\GoAgent]] has duplicate unique identifier which conflicts with [Agent located at [ Infrastructure - GO Build Server - WIN-KANQRBSIE3G, 10.132.44.244, C:\ GoAgent]] [Sep-12 15:56:38] So an agent is conflicting with itself. There are definitely no other agents on this machine. The servers that provide these build agents are created and destroyed on a daily basis and there are 6 of them - all built using cloud formation in exactly the same way and none of the other servers are reporting any errors. I suspect some kind of bug in GO but I am not sure how to further diagnose the issue. If anyone can shed any light on this problem I would be very grateful.
