Not able to restart stardog

[AJUSC]

I had my stardog server running when suddenly it got shutdown due to power running-out. Upon restarting i am getting the following exception and not able to restart the server. I am using 2.2.4:

Without seeing the entire stacktrace, it's hard to say for sure, but you can try repairing the system catalog:  `stardog-admin db repair system`

Mike
