sorry for the long delay in response, there were a few issues solved in later versions of ScheduledJob, can you verify this against latest 1.4.x? I've tried cherry-picking all of the crucial ones, like: and I'll try to verify this on my own as well.

I am still getting the same issue with
thanks for the info, will dig deeper into this one.
Thanks a lot any chance a potential fix could make it in 1.5?
if possible - yes, I'll try to backport it to 1.5
did you look into this? If not, let me know if you want me to pick it up and work on a PR
yeah, go ahead and ping me in the PR.
I just thought of something which might make sense. We've modified the error message to make it more "actionable", and the user can set a deadline to avoid running into this. However, the error message is still only controller level AFAIK and thus not exposed to the user. From the user's perspective, there is not way to tell why the CronJob is not scheduling the next instance. For these reasons, maybe we should also emit an event in the corresponding CronJob? I can send a small PR for this modification.
