The problem is lack of memory.
This process oom-killer is from kernel and it is used to free some memory by killing processes.

Lack of RAM causes this, but RAM can be real or swap.

Now why does this happen? The issue is with the app not being able to access RAM beyond real 4 GB. It is not even able to access swap and swap out. This happens because the kernel/OS port is for x86 and not for that particular arch, maybe the x86_64/amd64 port should be installed instead.

Before you upgrade your real RAM, check for RAM errors. Then install the x86_64/amd64 port instead.

HTH.
