Using >1 concurrent tasks will result in dropping frames


#1

Hello,
I’m observing a rather unpleasant behavior with the latest deadline version.

When I’m rendering with V-Ray standalone and I use more then one concurrent task. Deadline will randomly mark frames as completed with a render time of ~1 second.
V-Ray standalone will not write an output frame even though the task is marked as completed.

The behavior looks like this, the marked frames have a rendertime of 1 second and no output files, if I requeue the frames (even with the same machine) the frames will render fine:

If I do not use concurrent tasks at all, this behaviour will not occur.

Any Idea what it could be?
Unfortunately I could not “catch” exactly whats happening in the logs since it’s random.

Thank you
-Robert

Hey kwatts,
the task report for the highlighted tasks is empty, they are getting marked as completed but the log is empty:

I just saw that someone here has a very similar issue:

Thanks
