Grakn server stop takes too much time

Question

I'm trying to stop Grakn server but it doesn't stop. When I query status, it says both server and storage are running.

I thought it's related with this issue. However this issue is solved long before.

I did some operations like insert, match, delete with Python client. Is it possible one of them didn't close well?

I can't run any query on Python client or console now, it gives this error:

Unable to create connection to Grakn instance at localhost:48555
Cause: io.grpc.StatusRuntimeException
UNAVAILABLE: io exception

Answer 1

It's possible that the server has actually stopped but the terminal process doesn't know about it.

Grakn Core 1.8 runs as a Java process. You can check if there is a server instance by running:

jps

If there is a Grakn instance, it will be named GraknServer, and you can force quit it if necessary using kill.

After that you can restart Grakn using ./grakn server start as normal.
