Number of relaychain peers isn't limited

[stakeworks]

The max number of relaychain peers should be 40 with default settings:

  --out-peers <COUNT>
      Specify the number of outgoing connections we're trying to maintain
      [default: 8]

  --in-peers <COUNT>
      Maximum number of inbound full nodes peers
      [default: 32]

But this doesn't work, also explicit setting in-peers and out-peers for relaychain doesn't work.

What's your boot command?

[stakeworks]

ExecStart=/path/darwinia \
        --collator \
        --chain=crab \
        --base-path /basepath/ \
        --name 'StakeWorks | Crab | CMN02' \
        --execution wasm \
        --prometheus-port port \
        --listen-addr /ip4/xx.xx.xx.xx/tcp/port/ws \
        --listen-addr /ip6/xx:xx:xx:xx::1/tcp/port/ws \
        -- \
        --execution wasm \
        --chain=kusama \
        --base-path /basepath/ \
        --sync=warp \
        --state-pruning 1000 \
        --blocks-pruning 1000 \
        --out-peers 15 \
        --in-peers 35 

The in- and out-peers where added later, but had no effect

Same thing happened with the Interlay Kintsugi chain, after the update to Polkadot 0.9.38

Have you ever encountered this, @fewensa?

I think there are a lot of light nodes.

Try --in-peers-light 35.

[stakeworks]

I've tried this:

    ... 
    -- \
    --execution wasm \
    --chain=kusama \
    --base-path /basepath/ \
    --sync=warp \
    --state-pruning 1000 \
    --blocks-pruning 1000 \        
    --out-peers 15 \
    --in-peers 35 \
    --in-peers-light 35 \

But after a few minutes I already have over 300 peers.

There is nothing to do on our end.

This issue isn't related to light clients. There was a problem in 0.9.40 where the network event stream got clogged and displayed the number of peers incorrectly. This was fixed in 0.9.41
