Ever since we upgraded our four environments from 9.9.12 to 10.0.1 (Dev, QA, Stage, Prod), our clients lock up and go into a "not responding" state after making the simplest change such as attempting to edit a task, or even just opening a task by double-clicking on it. When it goes into this state, it takes several minutes of just letting it sit to be responsive again. We have found that restarting the VC service on the server will resolve this for a little while (few hours?). So far, we have attempted to resolve by uninstalling and reinstalling the server app.
The freeze up happens on both the client on our laptops and the client within the server. Server CPU/RAM utilization does not spike when the freeze happens.
Any ideas?
