> Key: GEODE-8874
> URL: https://issues.apache.org/jira/browse/GEODE-8874
> Project: Geode
> Issue Type: Bug
> Components: native client
> Reporter: Jakov Varenina
> Assignee: Jakov Varenina
> Priority: Major
>
> When native client increments *m_transactionId* above INT32_MAX(2147483647) then due to memory overflow the *m_transactionId* is set to negative value INT32_MIN(-2147483648). TransactionID (m_transactionId) is sent to the server as a part of transaction message.
> Currently server will interpret any negative value of transactionID (uniqID) as non-transactional traffic. Please notice that getTransactionID() actually retrieves uniqID value that is set by client.
> {code:java}
> /**
> * checks to see if this thread needs to masquerade as a transactional thread. clients after
> * GFE_66 should be able to start a transaction.
> *
> * @return true if thread should masquerade as a transactional thread.
> */
> protected boolean shouldMasqueradeForTx(Message clientMessage,
> ServerConnection serverConnection) {
> return serverConnection.getClientVersion().isNotOlderThan(KnownVersion.GFE_66)
> && clientMessage.getTransactionId() > TXManagerImpl.NOTX; // ---> NOTX is equal -1
> }
> {code}
> After overflow happens all subsequent commit actions from the client are rejected with exception:
