Distributed Processing Workflow and Monitor

Post by Noqras » Thu Mar 19, 2020 6:59 pm

I just started using the distributed processing feature and its been working very well. There are two things that I have noted however.

Currently I have two servers running ffastrans as a farm, very often now whenever I edit the workflow on one server it will actually disappear from the other server's GUI and then disappear altogether after saving the edited and shared workflow, I then have to import a backup. This is with both server's GUI's open, I don't know if that is the issue.

The second issue is minor, I have noticed for me at least that when I have ffmpeg processors running on both servers, when looking at it in the job monitor one of the jobs often disappears and then reappears a couple seconds later, it doesn't stop or anything, just disappears from the job list and comes back a bit later, doesn't affect the actual processing.

Hi Noqras,

Well that's not good! :-( Is the workflow issue behavior more normal than not?

The other issue with momentary disappearing jobs is known. It's related to how jobs are updated. I will try and come up with a fix for it but it's lower priority compared to other more critical bugs. But thanks for notifying :-)

It seems to be pretty normal, the scenario is this in testing:

Both servers open via RDP, both GUIs open, doesn't matter is that particular workflow is open on both or not, I make a change on server 1 to a workflow, save it, it disappears from the other server's GUI, I switch workflows on server 1 and then the saved workflow disappears there as well.
I import a backup, try to edit again, and usually it works that time.

Hi Noqras,

I'm struggeling with recreating the issue. You're writing that it usually works after importing a backup. Is all ok then or does it suddenly start removing the workflow again after edit?

Most of the time I can edit and save after that at least once before it disappears again. After that though it is likely to happen again it seems.

If you're not able to reproduce this one though I wouldn't worry about, I might have something else going on with my setup.
