This question already has an answer here:
When I start Geth on ubuntu with this command -
geth -rpc --syncmode="light" --rpcaddr 127.0.0.1 --rpccorsdomain "*" --rpcapi personal,web3,eth
it starts geth and with RPC I can create accounts and other things. But after some time geth throws many error continously and die after some time.
Error - Failed account unlock attempt
address=0x621C385fe616fBe096322E71d6f02631d520C1Ca err="could not decrypt key with given passphrase"
What is the reason and how to stop and solve this? pls help
