1. A method for providing high availability of a computer platform, comprising the steps of:

  • running at least one monitored process indicating its live state by periodically sending a heart-beat message and indicating a heart-beat frequency by inserting time information in the heart-beat message;

    running a fault-tolerant controller process (FTC) receiving the heart-beat message and reacting to said time information by modifying the frequency at which it expects the heart-beat message; and

    running an additional process and wherein the monitored process regularly sends the additional process a message and notifies the FTC that the additional process is dead when it receives an error code from an operating system after sending a message to the additional process.
