monetd shutdown error and starting error

shutdown error According to the monetd documentation example, my node m1 normally joins the network of node m0. After a period of time, m1 exits the operation and reports an error when exiting. Below is the run log.

The strange thing is that after the node joins the network, it always reports the warning message of the signature error during the synchronization process.
