When using Helia to send a large file, the connection was disconnected

[fastalks]

Step1

create unixfs to addfile on Node1 , then send CID to Node2.

helia = await createHelia(
    {
      libp2p,
      blockBrokers:[bitswap()]
    }
  )
const ufs = unixfs(helia)
const fileCID = await ufs.addFile({
    path:filePath,
    content: fileStream,
    mode: 0x755,
    mtime: {
      secs: BigInt(new Date().getMilliseconds()),
      nsecs: 0
    }
  });

Step2

cat File on Node2

 try{
    const ufs = unixfs(helia)
    const cid = CID.parse(cidString)
    const writeStream = fs.createWriteStream(outputPath);
    let receiveBytes = 0;
    for await (const chunk of ufs.cat(cid,{
      signal:AbortSignal.timeout(100 * 1000),
      onProgress:(evt)=>{
        const { bytesRead, totalBytes, fileSize } = evt.detail
        const bytesReadNumber = Number(bytesRead)
        const totalBytesNumber = Number(totalBytes)
        if (bytesReadNumber && totalBytesNumber) {
          const progress = bytesReadNumber / totalBytesNumber
          const fileId = cidString
          libp2pNode?.services.pubsub.publish('progress-notice',uint8ArrayFromString(JSON.stringify({fileId,progress})))
        }
        
      }
    })) {
      writeStream.write(chunk);
    }
    writeStream.end();
    console.log('File transfer complete');
  } catch(err) {
    console.log(err)
  }

The connection disconnects every time after transferring a few MB, with no errors

Any help would be greatly appreciated

How are you instantiating libp2p?

Can you please share logs by setting the DEBUG env var, as documented or programatically with the enable function exported by @libp2p/logger
