Hello, we are using spicedb as a permissions check middleware in our backend api with avg 15req/second, it performs bulk checks of size ~50 per request. We are seeing a lot of errors like:

rpc error: code = Unavailable desc = closing transport due to: connection error: desc = "error reading from server: EOF", received prior goaway: code: NO_ERROR, debug data: "max_age"

It's worth to mention that we have only 1 SpiceDB client in the backend, is that the right way? or do we have to create a new client connection on each request?
