Hello, back in the discussion after being traveling.
Interesting, because it shows like being the normal recvfrom() done on the internal socket, expecting to be no load there. I have seen the backtrace you sent in previous email and it is in the same recv function from the system. The process is waiting for packets on the memory socket. I will try to read more about and see if there is anything missing there.
