I think that it happens when clicking on the red square to stop debug inside the Debug View

nickboldt · 2019-07-24T15:46:37Z

Does this prevent you from doing anything, or is it just log clutter that should be cleaned up (error should be caught better) ?

slemeur · 2019-07-24T19:58:13Z

@tsmaeder : this lands into your team backlog, as something to try to reproduce.
As the steps to reproduce the issue are unclear -> backlog of 7.x

I detected no functional problem. I would say that it is jug log clutter that should be cleaned up.

tsmaeder · 2019-09-10T11:40:20Z

Need to analyze whether this is something that may happen (because timeout or something similar). If yes, write out a reasonable log message that makes clear this is nothing to worry about. If this is a problem, fix it or if too complicate defer for later implementation

Issues go stale after 180 days of inactivity. lifecycle/stale issues rot after an additional 7 days of inactivity and eventually close.

Mark the issue as fresh with /remove-lifecycle stale in a new comment.

If this issue is safe to close now please do so.

Moderators: Add lifecycle/frozen label to avoid stale mode.
