Folder healthy, but still get 410 Gone

[PRabahy]

I tried to add copy an item to the public folder on the public grid but received an error. I am able to "ls" the directory and when I run "check" it says it is healthy, but when I try to upload it errors out.

Trace from command line:

This might indicate that no servers were connected, insufficient servers were connected, the URI was corrupt, or that shares have been lost due to server departure, hard drive failure, or disk corruption. You should perform a filecheck on this object to learn more.
