I have spent hours troubleshooting with our partners for the foreign systems, and truthfully, haven’t got very far. The general observation is that some systems Cloverleaf seems to communicate well with, and others, not so well. By turning on the EO logging, you can tell alot about what is happening connection-wise, but in most cases it has come down to we send an ORU, but never get the ACK back. Sorry I don’t have any more useful suggestions.
