These are two different processes, so I can't think of any other reason
than that your kernel really is running out of memory.
Unfortunately net_connect_unix() does two syscalls, but the
out-of-memory most likely comes from socket(). Its manual page says:
ENOBUFS or ENOMEM
Insufficient memory is available. The socket cannot be created
until sufficient resources are freed.
I don't know if "resources" means more than just actual memory.
