This actually forces an new check out of the whole project in the TAC. This is a time consuming task.

It looks like the TAC has a problem with huge projects. One solution is to reduce the projects size by splitting the project.

I had a project with about 70 jobs - no problem at all and a project with 800 jobs  - always a problem. We have split to project into 3 different projects and now the TAC works more reliable (more - not 100%!) but the situation is much better than before.
