Hi Andreas, thanks for the response.
- I solved it by increasing the ram size from default 3000+ to 15000 MB.
- Also, when I execute this in parallel, and when set to maximum cores, this issue occurs. So, I set to 80% of the cores and the execution works flawlessly without any resource constraints.
- No issues with datasets it seem. I guess for some datasets , the calculation requires more resources and when it is not available, these issues occur.
- Regarding parallel, It is not working as expected . In many cases serialized OLCA calculations are faster than parallel executions . I do not how know it works in the background
