Comment 18

[Julien Pagès (:parkouss)]

Oh, this should be easy to fix. Just use mozfile.remove instead of os.remove (mozfile.remove is designed for this kind of issue). BTW, we should grep/replace every os.remove or os.unlink that way.

Comment 19

[Julien Pagès (:parkouss)]

Hm, a bit more complicated, because we are now using mozfile.remove, but still the issue happen.

Copied from the output of the last comment:

Looking before that in the log, we have the real issue:

So we are trying to kill the process but we fail (this is in a thread, so the exception is only printed but dot stop the program!). So the browser still have a handle on the log file, and this is why we can't remove it.

lets see how this bug works out, we have removed browser_output.txt (earlier errors) and now we get mozharness errors early on before launching the browser (as best as we can tell)

It's been nearly a month now - I really think this is fixed (previously we had the error in an interval of 5 days max).

Closing it as resolved.
