Hi Team,

We are in issue with linkerd and grpc. So to troubleshoot we wanted to get information on below questions.
what version of grpc is supported with linkerd 2.13.5?
Also is there a way to find where and how to configure the max concurrent process setting of grpc?
max_concurrent_streams i am looking for ?

Kindly help us with this. This help will be greatly appreciated?

Hi @mlagad

I’m not sure exactly what you mean by grpc version. Can you be more specific? I’m not aware of any versioning of the grpc protocol: https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md

The Linkerd proxy conforms to the HTTP2 specification, which means that it will respect any max_concurrent_streams settings received from a peer. Linkerd itself does not set a max_concurrent_streams value.
