Closing a session to one instrument drops entire grpc channel to all other instruments.

[RT-Tap]

Hi I've been trying to connect to multiple instruments via separate vi sessions on a single endpoint/server and treat each of these connections as their own session/connection and essentially be able to connect/disconnect to each individual device while keeping a grpc channel to the PXI open.

However calling .close() on any instrument session will just close all sessions/connections to every instrument on the PXI. I think this is due to the fact that all sessions to a single server share a single grpc channel and when you call close on an instrument driver session the grpc session will be closed as well.

For example lets say I connect to the PXI and use the utility manager protobuffer to query all available devices and then I connect to an RFSA and an RFSG by creating vi client sessions for each. But then if I call client.close(nifsg_types.CloseRequest(vi=vi)) on RFSG it will also close RFSA. Again I think that this is because all connections/channels to a single server share a single tcp connection and therefore single grpc channel and so when one session is closed the entire grpc connection is dropped/lost.

This is not very desirable. Is there anyway to get around this?
