To Reproduce
Steps to reproduce the behavior:

  1. Start Cortex (SHA or version)
  2. Wait 2 minutes

Environment:

  • Infrastructure: CentOS 7.4 amd64
  • Deployment tool: vscode debug

Storage Engine

@pstibrany Can you help me troubleshoot this problem?

We have observed this as well. It is caused by low gRPC keepalive settings (#3431). It turns out that settings also need to be applied on the server side, otherwise server will disconnect clients that are "pinging" it too often. (See #3431 (comment))

In your case, you see queriers being connected to frontend. It's likely that you don't have enough queries coming to the system, so queriers will start sending PING messages to frontend instead (at gRPC level). But default settings for gRPC server is that if client sends too many PING messages within 5 minutes, server will disconnect such client. That is where "transport is closing" error comes from.

This can be fixed by setting lower values on the server (in this case frontend) side, using new options available from weaveworks/common#205 (cortex PR #3524), specifically -server.grpc.keepalive.min-time-between-pings=10s and -server.grpc.keepalive.ping-without-stream-allowed=true.
