1. A method of operating a message processing system, the method comprising:

  • receiving at a first device including a processor, said first device being in the message processing system, a first message from a first system which sends messages to said message processing system, said first message being communicated via a first communications path, said first communications path including a shared high speed low latency link in said message processing system over which new transaction messages are communicated, said shared high speed low latency link being shared with other systems which send transaction messages to the message processing system;

    determining, in the first device, that said first system requires a message gap fill to fill a message gap; and

    in response to determining that said first system requires a message gap fill, sending, from the first device, a signal to a second device to trigger said second device to supply one or more previously transmitted messages to the first system via a second communications path to fill said message gap, said second device being separate from said first system, said second communications path being used to communicate previously transmitted messages to said first system to fill said message gap, said second communications path avoiding the shared high speed low latency link over which new transaction messages are communicated.
