Hi Andy, After looking over the code, I get you point related to the `Ignore` flag but this also means that this branch of the `switch` is dead code: https://github.com/xrootd/xrootd/blob/master/src/XrdCl/XrdClXRootDMsgHandler.cc#L560 Since such a response as you said in the comments is handled synchronously here: https://github.com/xrootd/xrootd/blob/master/src/XrdCl/XrdClStream.cc#L449 All this is true if a `kXR_attn` response can not contain an embedded `kXR_waitreps`. Can it? If not, what do you think about removing the dead case branch?
