z ciekawostek dodam, ze w logu strace jest taki flood:

(...)
getrlimit(RLIMIT_NOFILE, {rlim_cur=64*1024, rlim_max=64*1024}) = 0
close(65535)                            = -1 EBADF (Bad file descriptor)
close(65534)                            = -1 EBADF (Bad file descriptor)

close(3)                                = -1 EBADF (Bad file descriptor)

a potem juz sam zglaszany blad:
