My system was working well without an explicit heap setting until today. I was able to do all my work as before on the Intel version, but about 50% faster throughput.
Today I tried to update a 95MB Excel file with the Excel Writer node and got a heap error. The heap would extend to ~8GB by itself but no further. My Mac has 32GB of RAM, so I expect that it should/could extend further. Not sure if the built in heap setting has been increased from 2GB to 8GB or not…that’s my best guess.
I was able to work around the issue manually with separate Excel files, but will be good to get a handle on the heap settings as soon as possible.
