BackupPC should parse this last line and extract 0.138msec as
the round trip time.

To see exactly the command it is running and the output it gets,
run:

    su backuppc
    BackupPC_dump -f -v shipping

Hit ^C after you get past the ping output and parsed result.
What ping output do you get?

In the mean time increase $Conf{PingMaxMsec} to get backups
running again.
