eth_sendRawTransaction and eth_getBalance keep repeating and failing

An unexpected error occurred while executing "eth_sendRawTransaction" JSON-RPC method: Error: RPC request failed

these two errors keep showing up, my guess is that wallet will keep calling this rpc and rpc failed without sending error to wallet so that wallet will keep calling.

How to fix this issue? And how to reset?

I am unable to replicate the issue. Can you give more details about your setup? Are you using a custom RPC endpoint?

what I did is to
kevlar -p 3000 to start kevlar

and then add this to my network. I did two transactions on Curve and they are still pending while log in kevlar shows the errors above
