It looks like fd 2 is marked close-on-exec, so in child 2 is closed, because first open in child is:
open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 2
I assume this just causes chaos, because node exits in fairly short order, with no output.
Hello,
Please im running bittorrent client to download torrents but it doesn't start. When i check using 'strace -c ls' i found this :

I don't understand any thing , juste that there is a problem in the 'ioctl' .
What can i do please?
Thnak you.
