Just wondering if we could add a testcase around it. |
@dphulkar-msft This bug fix, to me, seems tricky to test because of its non-deterministic nature. I was able to repro the error the customer had without having a panic on my end. In some cases, it might panic, in others it might not. It boils down to the timing of closing a channel before sending a message down it. |

PR for GitHub issue #2703
Implemented a RWMutex to ensure exclusive access to critical parts of the codebase i.e channel closures and sends. The issue linked above is related specifically to the
xferDone
channel. Similar implementation was done for other channels injobStatusManager
with the mutually exclusive read and write locks.
