Java error "invalid memory access"

I got an error in processing Sentinel-2 C2RCC. It said about “java.lang.Error: Invalid memory access”. Have anyone knows what cases this error? Is that the problem of freezing in bulk processing?

Thank you in advance
Regards

Hi,

Yes, this can break your processing. But should actually only affect the product where this error happens. Can you reproduce this error? Does it happen only on one product or with multiple?

In general, it’s a strange error. Something seems to be wrong with the memory allocation done by NetCDF/jna. So, it is outside of the SNAP code base and writing to NetCDF works in general.

Unfortunately, the jna report does not give helpful indicators what the reason might be. Also, the internet gives no helping hand here. So, I can only do some guess work.

  • Maybe other application processes running in the background interfere with the data processing.
  • It could be that there is an issue with your memory
  • Maybe there is an issue in NetCDF implementation which occurs only in rare cases.

You can try it on other system or change the output format.
More help I can’t give at the moment, sorry

Thank you very much for your response. I appreciate all suggestions.
