----------------------------------------
Description:
I have a kubernetes environment where gremlin server is running as a server. While shutting down gremlin-server, I see below mentioned error

{code}
Steps carried out
1. server start -> *bin/gremlin-server.sh start*
2. Check whether graphs mentioned in gremlin-server.yaml have loaded properly or not
3. If failure, then stop the server by calling -> *bin/gremlin-server.sh stop*
4. Check logs5. Exit environment
