Hi Adrian, The problem likey is that you are getting a lot of requests at once and each time you get a request to create a file he oss.alloc directive says that 20% of the requested amount (or 4 GB if the amount was not specified) is to be reerved. If you get enough allocation requests the sum of the reserve amounts will exceed the available space. At that point you get the error. I assume the error comes from the server not the redirector.
