After upgrading to 1.7.2+release.
dcrwallet cannot provide services normally, and the rpc call always return
{
"jsonrpc": "2.0",
"result": null,
"error": {
"code": -4,
"message": "write tcp 127.0.0.1:43464->127.0.0.1:9109: write: connection reset by peer"
},
"id": "0"
}
After checking, it was found that the websocket connection between dcrwallet and dcrd was disconnected due to an error.

I checked all startup parameters and there is nowhere to fix it.
It may not be caused by the upgrade, but may be caused by the restart. After startup, dcrwallet will scan the transaction. dcrwallet currently manages around 60k addresses.
