Those lines are quite normal, at least usual, it's just looking for libc.so.6
in a specific list of paths. As you could see, it finally founds it in /lib:

IIRC I always see this when running a program in strace.

Well, there's nothing "unusual" here, and resources are not stressed (1GB
mem, very few buffers/swap used). I run some desktop/development stuff (mail,
browser, gcc, etc.) as I always did, and attempted to valgrind as it used to
work. I tried w/ all apps closed, this didn't help, as I expected.
