After the last unsuccessful attempt to reconnect to the same server, the client will then try to connect to other servers. When the client successfully reconnects to the same server or a different server, the HEARTBEAT_RETRY_FEATURE_FUNCTION callback is called, and the client attempts to re-checkout the feature. (By default, features can be re-checked out if their version is equal to or less than the version originally checked out. To specify that the feature version being re-checked out must exactly match the originally checked out version, you can enable LMX_OPT_EXACT_VERSION.)
The HEARTBEAT_RETRY_FEATURE_FUNCTION callback may be called many times, because LM-X will not stop retrying the checkout until all possible license servers have been tried. Every HEARTBEAT_RETRY_FEATURE_FUNCTION is followed by either HEARTBEAT_CHECKOUT_SUCCESS_FUNCTION or HEARTBEAT_CHECKOUT_FAILURE_FUNCTION.
