Ok so I checked the wu 21058, that were run 2 times on the same client (this is another issue that will not be discussed here) giving different results.

First I ran in standalone mode, getting the same results the client got once, then I found that the difference between the 2 client's outputs is that one of the two files have a single pcalg-run output repeated (the one starting in line 60584).

This is definitely an application issue, I guess is somewhat related to the checkpoint mechanism.

Ok. It may be a good idea to look at the logs(stderr) of both runs, and see if the issue is reproducible on the standalone app.
If it's not reproducible, we will need to upload a vew version of the application with better logging.

We found the bug, it was actually related to the checkpoint mechanism. We will fix it asap :)
