On sending a number of concurrent transactions to geth running a private network with a small number of mining peers , i notice that transaction hashes are generated for each of those transaction , but most of the time , some of them do not get mined and the getTransaction method for the hashes of these transaction returns null. Why is this occurring ?
The ratio of these transactions is almost 10 : 1 (total transactions : null transactions). All other transactions get successfully mined.
I am mining only on the peers whereas the node that generates transaction is not mining . What is wrong here ?
