I'm having trouble with an agent that is disconnected that I can't figure out how to reconnect. I believe it got disconnected when someone tried to manually stop a build that was in the middle of a huge SVN checkout. Now that build agent shows as disconnected with an inactivity reason of "Runs unknown build we're not aware of", and no amount of killing processes or rebooting the machine or restarting the service seems to help. I need that machine back online, but I'm pretty much lost for what to do to fix the problem at the moment. I did some searching and found that there was a bug related to this, but it was fixed quite a while ago. We are currently using TeamCity Professional 4.0 (build 8080).
Can anyone help me with this?
