```
Downloading the directory from s3 and untarring it I found 1036 files. The ulimit -n output says 1024. This is our team's best guess at a root cause. But the code fixed in the PR definitely is holding all the files open until the method closes: https://blog.learngoprogramming.com/gotchas-of-defer-in-go-1-8d070894cb01
Please note my go code abilities are not great and I did not test this. I just edited the file in github. All I did was remove the defer and put fileClose after the copy is done. Theoretically this should only hold one file open at a time now. Let me know if you want me to do any further steps.
Thank you,

If a PV already exists, wait for it, it's associated PVC, and associated
namespace to be deleted before attempting to restore it.

Instead of only removing the default token from a service account when
it already exists in the cluster, always remove it. If the service
account already exists, continue to do the merging logic.

We were checking for nil, but were getting back an empty
*unstructured.Unstructured{} instead, along with a NotFound error.
Change the logic to check for the NotFound error instead of a nil
object.
