Lots of "dovecot: auth: Error: auth client 0 disconnected with 1 pending requests: EOF" errors in error.log

I've recently upgraded to dovecot 2.3 and now my error.log is full of this message: dovecot: auth: Error: auth client 0 disconnected with 1 pending requests: EOF In earlier versions, this error was logged at a warning level. What is the rationale behind the elevation to error log level? May I suggest to revert this change?

(fyi: the code in question is in /src/auth/auth-client-connection.c)

static void auth_client_disconnected(struct auth_client_connection **_conn) { struct auth_client_connection *conn = *_conn; unsigned int request_count; int err;

    *_conn = NULL;

    if (conn->input->stream_errno != 0)
            err = conn->input->stream_errno;
    else if (conn->output->stream_errno != 0)
            err = conn->output->stream_errno;
    else
            err = 0;

    request_count = conn->request_handler == NULL ? 0 :
            auth_request_handler_get_request_count(conn->request_handler);
    if (request_count > 0) {
            e_error(conn->event, "auth client %u disconnected with %u "
                      "pending requests: %s", conn->pid, request_count,
                      err == 0 ? "EOF" : strerror(err));
    }
    auth_client_connection_destroy(&conn);

}
