P4 Task: attempt: 1 ERROR: P4: Task Exception: com.perforce.p4java.exception.ConnectionException: No open file stream in ClientSystemFileCommands.writeFile() [MSBuild] Skipping execution of recorder since overall result is 'FAILURE'

We had to downgrade from 1.10.0 back to 1.9.7. Most syncs of workspaces started to fail with version 1.10.0. As soon as we downgraded everything went back to normal and our workspace sync work perfectly again.

I can't really tell what the problem is, but either I see the above error, or files are simply missing, and subsequent builds are failing.
