At a guess, no tmpfs support, or it's not mounted at /dev/shm.

tmpfs on /dev/shm type tmpfs (rw)

Should be there.
And as you can see in the following tst-mutex2 sample, mmap2 generally
does work. But there is always one call, that doesn't work and which leads
to an error. I think, the programm wants to have too much memory - but why?

I would be very glad to get some hints to find the problem!
