We're getting lots of error messages that look like the example below. This exact error has come up 38 times in the last 30 minutes (583 in the last 12 hours). Other 'rename' errors of the same kind but a different URL, are also showing.
I hope the stack trace is useful. Let me know if I can help fix it.
