Hi, App act as client (1-1 Style SOCK_STREAM) App try to send 278 bytes of message. So you mean that, if socket has space for few bytes (say 1 or 2 bytes), lksctp will set POLLOUT event for fd, but since user application doesn;t know the underlying socket space available, it can write more than that but will fail with EAGAIN ?
