Hallo.
Ich erhalte manchmal beim nächtlichen Vollbackup solche Meldungen:

Code:
200    Dockerhost    FAILED    00:01:26    start failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

oder auch:

Code:
902    Ubuntu-18.04    FAILED    00:00:02    start failed: org.freedesktop.DBus.Error.Disconnected: Connection is closed

Das geschieht (auf den ersten Blick) nicht reproduzierbar -- was könnte die Ursache sein?
Danke.
 
hi,

was sieht man im syslog/journal auf dem zeitpunkt?
