Stardog server startup issue


I am trying to bring Stardog server up. However it is stuck up with below logs.

INFO  2020-11-20 15:31:16,171 [main] com.complexible.stardog.virtual.DefaultVirtualGraphRegistry:syncCache(313): Initializing virtual graph registry

Please let me know how to fix this.

Can you include some more details on what's happening? Is Stardog unresponsive at this point? What version are you running? What OS are you using?

I'm seeing this issue with an instance that is running on Ubuntu 18.04 with stardog 7.6.3 installed via the debian installer. I started seeing this issue after having an out of memory error when querying a large virtual graph.

Here is the error I saw:

INFO  2021-05-11 18:11:44,888 [main] com.complexible.stardog.virtual.DefaultVirtualGraphRegistry:syncCache(494): Initializing virtual graph registry

I let the server try to startup and it was pinned at 100% on 1 cpu for over 4 hours. Even using -v the only output I saw was the above in stardog.log.

Any thoughts on how to debug this?
