This looks very weird:
602001200000-602001210000 rw-p 00000000 00:00 0
602001210000-602001220000 rw-p 00000000 00:00 0
We have two adjacent mappings with the same perms
which are not merged by the kernel into one.
This is not what I typically see on my linux.
Is this some kind of modified kernel config or something?
If your kernel behaves this way no winder that mmap eventually fails.
