pandas 1.3.3 to_feather giving ArrowMemoryError - pandas

Question

I have a dataset of size around 270MB and I use the following to write to feather file:
df.reset_index().to_feather(feather_path)
This gives me an error :
File "C:\apps\Python\lib\site-packages\pandas\util\_decorators.py", line 207, in wrapper

pyarrow.lib.ArrowMemoryError: realloc of size 3221225472 failed
Note : This works well in PyCharm. No issues writing the feather file.
But when the python program is called in a Windows batch file like:
call python "myprogram.py"
and when I schedule the batch file in a task using Task Scheduler it fails with above memory error.
PyArrow version is 5.0.0 if that helps.
Any ideas please?
