For example, a wallet transaction that was BIP-125-replaced in the mempool prior to this RPC may not yet be reflected as such in this RPC response. + +## Limitations + +There is a known issue in the JSON-RPC interface that can cause a node to crash if +too many http connections are being opened at the same time because the system runs +out of available file descriptors. To prevent this from happening you might +want to increase the number of maximum allowed file descriptors in your system +and try to prevent opening too many connections to your JSON-RPC interface at the +same time if this is under your control. It is hard to give general advice +since this depends on your system but if you make several hundred requests at +once you are definitely at risk of encountering this issue. |
