Basically it seems that we are submitting chained transactions in one thread and may create them in a separate thread. Is this a supported use case for TransactionChains? </p> <p>Just from examining the code in the databroker I can see why this exception could happen. There is no synchronization between creating a transaction on a chain and submitting that transaction which can result in some application thread attempting to create a transaction on a chain before the cohorts on the previous transaction being made ready.</p> <p>Finally I was able to reproduce the problem.

That should not cause this issue.</p> <p>You're right Martin, incorrect analysis on my part.</p> <p>The primary exception reported in this bug is a red herring.</p> <p>The root cause of this issue are some exceptions that happen before. I've captured those exceptions in this gist -&gt; <a href="https://gist.github.com/moizr/4205d9c6b47a655e411f" class="external-link" target="_blank" rel="nofollow noopener">https://gist.github.com/moizr/4205d9c6b47a655e411f</a></p> <p>Initially a ModifiedNodeDoesNotExist happens on a couple of transactions. This causes the transaction chains to fail. Because of this the TransactionChainManager's onTransactionFailed method is called. Over there we attempt to close the txChainFactory this results in the following exception. This exception does not allow a new transaction chain to get created. So any subsequent transaction that gets created on the old chain results in the "Previous transaction is not ready yet exception"</p> <p>2015-05-08 21:43:37,872 | ERROR | ntLoopGroup-6-10 |
