    Hello,

    I seem to have a problem serving files with
    lighttpd from non local (smbfs) filesystem.
    Lighttpd tries to use sendfile(2) but, it returns
    with -1 and errno "Operation not supported",
    but i can't find this error in the documented errors
    on the manpage.
    Forcing lighttpd to not use sendfile fixes the problem,
    but i would really like to use it...

    Any suggestions?

     40793 lighttpd CALL open(0x8089c80,0,0x80bac00)
     40793 lighttpd NAMI "/usr/local/www/data/stuff/downloads/some_file.txt"
     40793 lighttpd RET open 8
     40793 lighttpd CALL sendfile(0x8,0x7,0,0,0x1b22,0,0xbfbfc600,0)
     40793 lighttpd RET sendfile -1 errno 45 Operation not supported
     40793 lighttpd CALL write(0x6,0x8089400,0x5d)
     40793 lighttpd GIO fd 6 wrote 93 bytes
           "2005-10-29 08:43:09: (network_freebsd_sendfile.c.174) sendfile:
     Operation not supported 45
           "
     40793 lighttpd RET write 93/0x5d
     40793 lighttpd CALL close(0x8)

    Here /usr/local/www/data/stuff/downloads is a smbfs mount.
    If the file is local everything works as expected.
