In the last couple of weeks, I've encountered a problem in our TFS 2010 builds: A TFS Build Controller becomes unavailable for seemingly no reason.
I looked into the Event Viewer of the Controller machine, TFS application machine and the VM Host - not a clue.
The log of the controller machine shows the following lines every time before the controller became unavailable:
"... *** TFS Server: request to Update BuildController.
... PENDING+ '[Controller Name]': Restart.
... EXECUTE: Restarting '[Controller Name]' from Building. Delayed. Service should stop after stopping running builds.
...PENDING+ '[Controller Name]': Stop.
...Testing a connection from BuildController to BuildAgent '[Agent Name]'..."
Can anyone explain:
What does it mean?
What can I do about it?
Thanks a lot!
