<p>When i sendrawtransaction to bitcoind, i get error (exceptions) <code>18: txn-mempool-conflict</code> (use Bitcoin JSON-RPC <a href="https://github.com/denpamusic/php-bitcoinrpc" rel="nofollow noreferrer">denpamusic/php-bitcoinrpc</a>)
But the transaction is sent to the network and is subsequently confirmed.</p>

<p>Example one decoded transaction : <a href="https://jsfiddle.net/rn58a4j6/" rel="nofollow noreferrer">https://jsfiddle.net/rn58a4j6/</a></p>

(Asked by: username_0 on 2018-08-29)

When i sendrawtransaction to bitcoind, i get error (exceptions) `18: txn-mempool-conflict` (use Bitcoin JSON-RPC [denpamusic/php-bitcoinrpc](https://github.com/denpamusic/php-bitcoinrpc))
But the transaction is sent to the network and is subsequently confirmed.

Example one decoded transaction : <https://jsfiddle.net/rn58a4j6/>

then i send this transaction:
94ec12fc463230b4285a29b047608627c05572a4c6eabe6688a201ce49ae72f7
