@gumond : thanks a lot for reporting this issue! Just some additional observations: - EOS is not using `PostMaster::ForceDisconnect` so the socket-handler deletion comes from the connection TTL - before actually deleting the `Stream` object (and its socket handlers) the client calls `AsyncSocketHandler::Close` that, in turn, remove the socket from the poller https://github.com/xrootd/xrootd/blob/7c6dfb6b74ea30121e92e257c909dd6b9eed9bf6/src/XrdCl/XrdClAsyncSocketHandler.cc#L183-L194 - it seems to me there must be a race-condition in the poller itself (???) -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1590#issuecomment-1012990769 You are receiving this because you are subscribed to this thread.
