  • 0

We have a TFS2010 setup with a single controller and 2 agents running on the same build machine. Yesterday the build server stopped running 2 concurrent builds and just let one agent do the work. I’ve tried to restart the controller and agents but with no lock. There’s no pattern and both agents are doing work – just one at a time. I’ve added a new agent today (same machine) and it can now pick up 2 concurrent builds – still got one lazy agent. Any thoughts?

New Info:
When I have 2 running builds and a couple in the queue (NB with 3 agents in total) and I change the priority to high – it starts to build on the last agent!?

    Ok – so an invalid entry in tbl_BuildQueue in the TFS database was the reason.
    Normal Priority Builds Will Not Build in TFS 2010

    Quick fix is to delete the entries in tbl_BuildQueue which have a DefinitionId that doesn’t exist.

    SELECT * FROM [Tfs_Default].[dbo].[tbl_BuildQueue] where DefinitionId not in (select DefinitionId from tbl_BuildDefinition)
