File i was playing with had 52Mb, i think i found something : 

....
open("/var/spool/news/cycbuff/one", O_RDONLY) = 5
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
shmat(5, 0x2, 0x1) = ?
shmat(5, 0x2, 0x2) = ?
lseek(5, 0, SEEK_SET) = 0
read(5, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 192) =
192
lseek(5, 0, SEEK_SET) = 0
brk(0x808e000)                          = 0x808e000
time([1002009053]) = 1002009053
getpid() = 24389
rt_sigaction(SIGPIPE, {0x401cfe08, [], 0x4000000}, {SIG_DFL}, 8) = 0
send(4, "<60>Oct  2 09:50:53 innfeed[2438"..., 97, 0)   = 97
rt_sigaction(SIGPIPE, {SIG_DFL}, NULL, 8) = 0
lseek(5, 0, SEEK_SET)                                = 0
time(NULL)   = 1002009053
write(5, "CBuf3\0\0\0ONE\0\0\0\0\0\0\0\0\0\0\0\0\0/var/spo"..., 192)
= -1 EBADF (Bad file descriptor)

dunno why inn open it read only and then try to write to it.
