I'm trying to calibrate some Sentinel L1C products to get level 2 data, but I always end up with the following message. Any idea what could cause that?

I have tested it with sen2cor 2.8.0 and sen2cor 2.9.0 with the same result. The product I'm working with is S2B_MSIL1C_20180421T100029_N0206_R122_T33UVR_20180421T120642.SAFE if that could be of any interest.

Okay, the problem was that I ran out of RAM. I would appreciate better error messages from sen2cor though, but yes, it was so simple.
