> 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.

> std::atomic<int32_t> TXId::m_transactionId(1);
> TXId::TXId() : m_TXId(m_transactionId++) {}
> {code}
> Currently server will interpret any negative value of transactionID as
> non-transactional traffic.
