Backoff retry delay in status check is increasing to hours rendering services offline about spring-boot-admin HOT 5 OPEN

yeah, this is the behavior I observed. You can reproduce it by running my gist, it closely resembles the code in IntervalCheck. It randomly simulates a timeout, then there may be few successful checks, then timeout again. With each retry delay becomes longer and never goes back to zero

Hi @eugene-sadovsky ,

that the retry time increases is intended behaviour. But you are right that the waiting time might get too high.
We introduced a new property for maxBackoff, so you can configure this on your own. The default maxBackoff for status check is now 60 seconds.

thank you for the quick response 🙇🏼

I think the main issue is that back-off time is never reset back to zero after successful retry. It will just saturate to maxBackoff and stay like this for the lifetime of the process. This still solves my issue, thank you 👍🏼

if this is really true that would be a bug in project reactor I think
