title: Transactions created using web3.py are stuck in geth queue and not broadcasted to rinkeby
body: <p>I am running a geth node synched to rinkeby network. I set up some automated services that filter solidity events and create transactions(web3.py) when certain events are received. This worked fine for a while, but at the moment all my new transactions are stuck in geth's queue. I can see them if I do txpool.content.pending['0x190Af0A202e7464340A140D6C59ee755b6D27829'], or eth.pendingTransactions. However, I cannot see my transactions at all on etherscan which makes me thing geth didn't broadcast to network.</p>
  
  <p>I tried overwriting the first transaction stuck by making a new one with the same nonce. I tried clean reinstalling geth. I tried waiting. I am out of ideas.
  Please help.</p>
