> While testing, I kept the server up and tried connecting from cli on various
> intervals while no other connections were being opened to the server. Works
> perfectly fine with intervals of 1,2 hours. But when server was kept idle for
> say a day, trying connecting with cli gives the following error:
> {noformat}
> Caused by: java.sql.SQLException: Already closed.
