Ethermint: tags v0.2.0
Ubuntu 18.04 64bit

Steps to reproduce:

1. make install
2. ./init.sh
3. ethermintcli rest-server --laddr "tcp://localhost:8545" --unlock-key mykey --chain-id "ethermint-1"
4. run below JavaScript to send transactions(customize LOOP, ADDR_FROM, IPADDR).

/////////////////////
// send txs
const LOOP=50;
// ethermintcli q auth account $(ethermintcli keys show mykey -a) -o json | jq -r .value.eth_address
const ADDR_FROM="0xAc7eBb5efF7c508F44F846a8C9C2Eb9dC796CCfB";
// ethermintcli --laddr
const IPADDR='http://localhost:8545';
/////////////////////


const Web3 = require('web3');
const web3 = new Web3();
web3.setProvider(new web3.providers.HttpProvider(IPADDR));

const fn = async() => {
    let nonce = await web3.eth.getTransactionCount(ADDR_FROM);
    console.log("nonce=" + nonce);
    for (let loop=0; loop < LOOP; loop++) {
        const tx = {from: ADDR_FROM, to:"0x00112233445566778899aabbccddeeff00112233", value:"100", gasPrice:"1", nonce: nonce};
        web3.eth.sendTransaction(tx, function(err, hash) {
            if (!err) {
                console.log("hash=" + hash);
            } else {
                console.log("err=" + err);
            }
        })
        .on('receipt', function(receipt){
            console.log('receipt=' + JSON.stringify(receipt.transactionHash));
        })
        nonce++;
    }
}
fn();

Expected behavior: [What you expected to happen]

receive all transaction receipts.

Actual behavior: [What actually happened]

sometime fail receive transaction receipts but not detect error.

Additional info: [Include gist of relevant config, logs, etc.]

Ethermint v0.1.0 too.

If the value of LOOP is small(1~3), it is often successful.

I got similar issue when send multiple transactions at the same time. I got error message:

The error message indicate the nonce is wrong.

I don't need the specific order of each transaction where I don't set the nonce value. Can I use the internal nonce count to padding each transaction in the block? The nonce will be arranged properly in geth that I don't need to set for each transaction when the order is not important for my program.
