> While cycling through and processing files using open_dataset(..., format =
> "feather") in R, the function hangs randomly and will not proceed to the next
> file. The freeze does not appear at the same file each time, additionally,
> the same function freezes when used one on occasion.
> When open_dataset hangs the only way to get R to stop is using Task Manager
> as Rstudio becomes totally unresponsive.
