Sasha,

All of our engineers uses 32 bit machine for development.
It's serious problem now.

I think we have to roll back this change.

Thanks,
Michael Kim.

Anuj,

Please try to set vm.mmap_min_addr=0 and see if it help a bit.
In general, it's known that qemu on 32 bit systems would misbehave randomly
in case of shortage of RAM and potentially due to other combinations of
libraries that it tries to run.
We had discussed that topic some time ago in the mailing list, mentioning
that unless those issues fixed by someone who knows arm and qemu well, it
would be no way to support 32 bit systems.
