Version

0.17.0-rc1

Config

> ipfs config --json Swarm.ConnMgr # these are values used in Kubo node managed by Brave
{
  "GracePeriod": "20s",
  "HighWater": 40,
  "LowWater": 20,
  "Type": "basic"
}

$ ipfs config --json Experimental.AcceleratedDHTClient
false

Description

IPFS Desktop and Brave run with lowered ConnMgr settings such as HighWater and LowWater.

Running 0.17.0-rc1 with

"HighWater": 40,
"LowWater": 20,

and opening /ipns/en.wikipedia-on-ipfs.org/wiki/ on empty repo produces a wall of errors and seems to break DHT-based content routing (bitswap works, but content that requires DHT rarely loads, browser timeouts).

How to reproduce

  1. Install 0.17.0-rc1, make sure repo is empty
  2. Set "HighWater": 40 and "LowWater": 20
  3. Restart node
  4. Try browsing websites that are not cached locally (try using /ipns/en.wikipedia-on-ipfs.org/wiki/ – walk from article to article)
  5. Observe stdout / logs + the delay in initial page loads (+ occasional timeout in browser)

How to fix?

  • I feel we need to create desktop profile that is fine-tuned for Desktop and Brave, and switch desktop use cases to that profile.
    • Perhaps it should have HighWater set bit higher? (iiuc we limit connection number based on this value) so we dont sabotage DHT walk and avoid ERRORs in logs?

@lidel: you listed

$ ipfs config --json Experimental.AcceleratedDHTClient
true

Is Experimental.AcceleratedDHTClient enabled? If so, I expect that is the culprit as that will quickly consume connections.

If a HighWater is set, we set the system scope's maxConns to 2*HighWater:

kubo/core/node/libp2p/rcmgr_defaults.go

Line 203 in 254d81a

defaultLimitConfig.System.Conns = 2 * cfg.ConnMgr.HighWater

@ipfs/kubo-maintainers : can we please get others to reproduce this so we can figure out our path forward on 2022-11-14 during standup.

This should be fixed with #9407 if we are using acceleratedDHT on that config too.
