Since (rough estimation) the heavy modification of the scheduler we can regularly observe the following error appear in the openQA log files:

[Wed Aug 23 09:56:24 2017] [11197:error] 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.

Unfortunately I cannot see what exactly is causing the issue here.

Suggestions on how to improve this message:¶

• If possible, include more specific reasons for this (what is the context of the message? What did the worker try to do?)

If this message is critical (not self recovering):

• Add hints where an admin could look for more information
• Expand message to explain the admin: "Hey, something just broke - you need to interact"

If this message should just inform the admin:

• Decrease log level to at max "warn"
