>          Issue Type: Bug
>          Components: gRPC

> I started an Ozone cluster on Kubernetes and started a freon test (ozone 
> freon ockg -n10000)
> After a while I found that the one freon instance is not creating keys any 
> more. I checked the om RPC endpoint with ozone insight and no RPC messages 
> has been arrived.
> Based on the jstack output we have a deadlock between 
> PeerProxyMap.handleException and GrpcClientRpc.sendRequestAsync.
> I am not sure (yet) what is the exact problem, but based on the stack traces 
> It seems to be Ratis related.
