What I find curious is, that it reads the correct command line and then opens

The first read is from is_kernel_thread().
The second read is from show_pid_array() -> get_process_cmdline().
I checked the code, but could not see any reason for this on the first look.
I did not see any mmap in the code causing this nor any reason, why this should
be
triggered by any libc function...
malloc() uses mmap for big allocations. I asked about COLUMNS because I
suspected this line in get_process_cmdline() was doing the big
allocations on your system:
r = new(char, max_length);
