Dear,
I have a problem running Sentinel-2 C2RCC. It seems freezing at 90% of processing. I do not have any ideas what is the issue.
Here is how I process.

What’s you processing environment? How much RAM do you have available?
I you are low on memory it can happen that the processing gets very slow or even enters an endless loop.
It would also help if you can provide the C2RCC configuration you are using.
You could disable some of the outputs the C2RCC can calculate. For example, the calculation is the uncertainties is quite expensive.
I have RAM 32 GB. I try to process Sentinel-3 C2RCC correction and it works.
The graphic card may be the problem, I got this error log said about Java problem
hs_err_pid16760.log (33.5 KB). The computer has NVIDIA Qudro K420 graphic card, and it is a bit old. What do you think, why it works for Sentinel-3 but not Sentinel-2?
And, here is properties C2RCC that I used
S2_MSI_60m_indreOslofjord.properties (472 Bytes)
Thank you in advance
32Gb should be sufficient.
If you have increased the amount of memory after SNAP installation you might need to adapt the value SNAP can use. (see FAQ)
The graphics card should not be the problem. It is not used for processing.
In the error log it is said:
# Problematic frame:
# C [hdf5.dll+0x8d153]
Do you write to HDF5? Maybe this is the problem.
You can try NetCDF4-CF instead.
No, I write to NetCDF4-BEAM.
