Hello Sen4CAP Team,

Recenlty, I got some errors with L2-S1 Pre-Processing but not for all of the jobs, just some of them. Exit code is 137, during the first step : Calibration 1-1.

Hello,

The above code (137) is given by Java Virtual Machine in case of OutOfMemory errors.
If you do not have too much memory on your machine, you could try decreasing the parallelism in the S1 pre-processing:

processor.l2s1.parallelism
processor.l2s1.gpt.parallelism
processor.l2s1.parallel.steps.enabled

Best regards,
Cosmin
