Dear Reader,

We are a joint research team from the University of Zurich, Switzerland* and Mozilla** and are building a tool to automatically recognize the type of an intermittent-failure, such as the one here.

By automatically recognizing the type of failure, the tool should provide a starting point for the bug fixing process. To evaluate and improve the tool, we kindly ask your feedback.
    
Tool Result - this intermittent-failure is most likely affected by a:
Test Timeout: This includes test failures in which a single test case or the whole test suite timed out. This might be due to an unresponsive or slow target system (e.g. either the system that executes the tests or the os itself), a test suite which has grown too large causing intermittent-timeouts or a timeout threshold for a process, thread, function call which was set too small/too large.

Feedback: 
1. Did the tool correctly recognize the type of intermittent-failure? (please also explain why or why not)
2. Did the information from the tool help your analysis, the bug fixing process, or anything in the process? (please also let us know how the tool was useful and/or what would improve the tool's usefulness for you)

Thank you very much for your help!
