Hello, "when the both channels in client protocol is disconnected, fd's are marked as bad" in git tree seems to be more problematic that before. Before : Two server , client open a file -> Server 1 down -> client ok -> Server 1 restart -> client ok -> Server 2 down -> client not ok ( BAD FD) because of not reopen file ( known bug) Now : Two server , client open a file -> Server 1 down -> client ok -> Server 1 restart -> client NOT OK Regards, Nicolas P.
