May I know what does this transaction mean? I am running this inside my private node. Running the same transaction repeatedly none stop. Sending on average 10 transactions / sec. So I had to keep track of the nonce.

But suddenly the transaction below just stopped and refused to process. Query transaction receipt just return null.

May I know what might had gone wrong?

Did I skipped one nonce? How can I tell if I had really skipped one nonce?

    What does eth.getTransactionCount("0xc8caa71c16299b40b8579742a27ee53162886040") returns? Perhaps your node skiped a nonce? – Ismael Sep 3 '18 at 17:28
  • Yes. Finally I realized what had gone wrong. The getTransactionCount returns little endian whereas Windows uses Big endian byte array. I had skipped. – s k Sep 4 '18 at 5:03

The eth.getTransaction() details that you have posted shows blockNumber: null.

It implies that the transaction with the transaction hash "0xb992cfa1e25268de903d54196c1efa1908fcaf900a304db2bde14c1315461dca" has not been mined into a block or you could say added into a block.

If you are using Ethereum's PoW as a consensus algorithm then it takes 15 seconds to mine a block, and as you said 10 transactions on an average, it is clear that you tried fetching details of a transaction that was not yet mined.

  • It had been there for more than 10 minutes. That is why I feel strange. This problem gone when I tried to limit the rate of transaction to more than 15sec. If I send many transactions in less than 15 sec, this problem will come back again. There might have some threading issues. – s k Sep 1 '18 at 0:32
