Hello, I have a situation where I'm trying to set the send and receive buffer sizes on a socket to large values like 1 MB or so (dont ask why :-), simple reason being we need it); and setsockopt for setting the buffer sizes seems to fail with ENOBUFS. On looking at the code in uipc_socket.c where it handles the SO_SNDBUF & SO_RCVBUF options, and the code in uipc_socket2.c where it actually tries to reserve space (in sbreserve function_, the issue seems to be a limit imposed by the code to approx 227K or so [ sb_max(=256) * MCLBYTES / (MSIZE + MCLBYTES) ; which works out to approx 227 K on my platform] Was wondering if anyone could explain as to why this limit is there ? Thanks in advance, Dinesh Nambisan
