Virtuoso recovery from license server interruption?

drdanmc

If the connection to the license server gets interrupted, Virtuoso will say "Virtuoso has lost connection to the license servers and will become unresponsive in 5 minutes.  Save your data now and then restore license server connection in order to re-obtain the required licenses.  List of timed out licenses: ....".  If it takes more than 5 minutes for restoring the license server (network issue, needing reboot of something, etc), is there a way to tell the now unresponsive Virtuoso that it should go and try again?  It seems when I get in this state I end up having to kill Virtuoso, lose things like unsaved ADE states, and start over.  It doesn't happen a lot for me, but it is always really annoying when it does.

  • You get about 20 minutes of grace time if the license server goes away (only with the licenses you already have checked out of course) - and these periodic popups (there's one at 10 minutes, then one at 5 minutes to go, then another when it finally becomes unresponsive). I just did some testing by killing my license server and see this behaviour, and do in fact see it recover when the license server got finally restarted. I'm not sure there's a way to "kick" virtuoso to check immediately though.
