Transaction Hash Returned but Not Broadcasted Automatically

[J1a-wei]

Hi Geth Team,

I've encountered an issue where Geth returns a transaction hash after sending a transaction, but the transaction does not seem to be broadcasted to the network. As a result, the transaction only appears on the blockchain after manually broadcasting it using a block explorer.

• What might be causing Geth to return a transaction hash but not broadcast the transaction?
• Are there any configuration parameters that can be optimized to prevent this issue?

Geth version: v1.14.3
