The default server configuration is set to start the application layer on the first request. This reduces startup overhead during normal operation (takes approximately 0.5 seconds).
In some cases, however, this behavior is not ideal — the first request can then take approximately 20 seconds. For this reason, it is possible to configure the accounting core to start automatically after the server starts.
Simply edit the file flexibee-server.xml (e.g. /etc/flexibee/flexibee-server.xml) and add true.
