Graceful sthutdown or reposerver

Is there a command or utility to gracefully shutdown the reposerver ?
After the configuration is done using, reposerver is started using The only option i know to stop the reposerver is to kill the java process. This doesnt seem to be a graceful shutdown tho. Wondering if there is a procedure to smoothly shutdown the reposerver. It is observed if the reposerver is started using and on stopping the server using STOP button of the UI, log msgs are found like reposerver is shutting down. This sounds to be a smooth shut down. Killing the unix java process doesnt log anything to the reposerver log.

Appreciate any pointers. Thanks.

I heard from wM support, there is no option of gracefully shutting down the reposerver.
