Here is another Tester story for you!

Tester: We have a problem with the application and it says that we cant process the queue to store the objects in the database.
Me: Can we reproduce it easily?
Tester: Yes..
Me: Ok, I'll add some debug for you so that you can see the error and the worker status more easily.
Tester: Great!

<10 minutes later>
After adding the debug output and installing it on his test cluster this happens...
Me: The debug version is installed.
Tester: Ok, great!
Me: How fast does it take to reproduce?
Tester: Well... It happened this morning at 9
Me: Ok..? But are you able to reproduce the issue at all?
Tester: No... i don't think so...
