I'm running a private network with one miner and I have the problem that if I send too many transactions from a node, those transactions are not getting mined.
For example: If I send one transaction every 6 seconds, then not a single transaction gets mined. If I send one transaction every 30 seconds then everything works fine.
I send a transaction with nodejs like this:
instance.myFunction(data, {from: account.address, gas: 4000000}, function(error, result) {
// do something
});
The transactions just pile up and not getting mined by the miner.
Here are for example two transactions:

I don't understand, why it's not working. I don't think one transaction every 5 second is a lot, they should get included into one block.
I'm using web3 version 0.20.0.
update: to make things even more weird, it is sometimes actually working but sometimes it's not - seems like completely random to me. I can see in the console that the transactions are sent, I can also see, that new blocks are generated and synced with my node - once it stopped working, I have to restart the node.
update: I tried to override the nonce manually but that didn't helped. All transactions are just queued in the transaction pool:
