I'm doing a load test on MC 2.0.2. Using a script I wrote a raw transaction having about 100 inputs and 100 outputs.
I signed it offline using a cold node and then I sent in the network with sendrawtransaction.
The transaction is accepted by the node and I got the txid back but I realized it is still in the mempool. I found that in the debug.log file of all the nodes in the network I have the following ERROR line:
2021-02-07 22:29:58 ERROR: AcceptToMemoryPool : free transaction rejected by rate limiter
Could you kindly explain the the meaning and the reason why the transaction is not mined by any miner?
