It's worthy of note, I have an existing node running on the 'polkadot' binary provided by the project's apt repo, also on Ubuntu 20.04 LTS. When I copy the .json file above to that node and launch with the polkadot binary, the error output identical to above. |

If you want to start a parachain, use |

I wouldn't say I'm trying to "start" a parachain. I'm trying to run a node on asset-hub-polkadot. It doesn't work with the 'polkadot' binary as aforementioned. And I believe i've already tried with 'polkadot-parachain' with exactly the same result. Perhaps you could point to a guide showing how to get this going, because I don't think one exists and there is a gaping hole in the documentation in this regard. |

Thanks for the reply. Now it seems we're getting somewhere :) Note that I quoted this exact URL in my bug report. I hope you'll forgive my ignorance, mostly not knowing how things are done in the "polkadot world". But I am directed by your URL that I should build a binary called I've tried building As per above I have already tried the Finally, for the sake of completeness, I did build the Is there anything else I should try, or shall we reopen and call this one a bug? Thanks again. :) |

Fascinating. After running the above command, cargo decided to build me a binary called |

Okay perfect! |

Whereas this issue is still marked "open", and I'd like to point out that there is another glaring error in the docs: I see no indication as to what kind of system resources I have Kusama and Polkadot nodes running (on the Ubuntu 20.04 repo binary) for a few days now, both seem to only actually need about 1.6GB of RAM: and I am currently seeing an out-of-memory condition on Thanks. |

This is the entire output, including version number. Note that it is quite slow to initialize the database, perhaps 5 minutes, which is much slower than my full archives of Polkadot and Kusama btw. Specifically I mean that the stage that says |

See below for the last 100 lines of the console log. If you need the whole thing I suppose I can pastebin it. |

Out of curiosity I re-launched this VM with 25GB of RAM, all other specs remaining equal to before. I no longer get an out-of-memory condition when launching. However, I see that despite having plenty of peers, the Parachain is no longer being updated. I'm mentioning this in case it is somehow connected to the out-of-memory problem. Unless we need more Relaychain blocks in order to advance the Parachain? See below. |
