Also, attempt reconnect once if DB access fails:
>               /*
>                * Try once to reconnect.  In theory, the caller (client)
>                * will retry the tmcc call and we will reconnect and
>                * everything will be fine.  The problem is that the
>                * client may get a different tmcd process each time,
>                * and every one of those will fail once before
>                * reconnecting.  Hence, the client could wind up failing
>                * even if it retried.
