Dgraph mutation hangs forever

My dgraph installation is on a single host machine. I am having an issue with dgraph mutation queries. Under a high throughput after couple hundred mutations with CommitNow, the mutation query hangs (unless I use context timeout) forever, and the same connection doesn’t work anymore.

I have seen this behavior when I use commitNow with mutation. With --ludicrous-mode or removing the commitNow flag, I don’t see the connection issue.

Info about my installation and environment:

Dgraph Version: 20.11.1
Dgraph go clients:

grpc client:
