I've got a strange problem, and I have no clue where to start searching, so I'd hope you could give me some directions.
I have a REP socket to receiving messages from a DEALER socket via an ipc connection. The first few (2-5) messages sent by the DEALER are never received. I have never noticed a missing message after the first one has been received.
Perhaps it is important that to mention that the process sending the messages sets up a socket, sends one message and terminates, so each message is coming from a different process.
This problem does not occur when the message is sent from the same process, either on an ipc or inproc connection.
