Solved! Margherita pointed out that the original script was messing up the values of the projection because in one of the testing versions I was using integer values instead of characters for the region resolution parameter, and since then the script started giving this error, which I did not noticed. That is why it was running in one machine and not in the other one...
This is the test script about parallel computing using different regions [1]. I will test it and let you know if it works with a large segmentation processing job. Thank you very much!
