Georg Henzler commented on SLING-8939:
--------------------------------------
bq. health checks were executed every minute by default
by default HCs are only executed when requested, that means there is some
client requesting every minute.
if that client (could be http, JMX or via API) sets the option
forceInstantExecution, you get the described behavior. Can you check if that’s
the case in your setup [~muenkti] ?

> Key: SLING-8939
> URL: https://issues.apache.org/jira/browse/SLING-8939
> Project: Sling
> Issue Type: Bug
> Components: Health Check
> Reporter: Timo Münkenwarf
> Priority: Major
>
> Hello,
> I currently observed something with async health checks.
> We recently migrated to AEM6.5 and observed, that our health checks were
> executed every minute by default. Because this was to often, I tried to use
> asyncCronExpression.
> This makes our Health Checks executed as defined in the asyncCronExpression,
> but additionally they are still executed every minute.
> Is this a bug or how can I let my Health Checks _only_ be executed as defined
> in the asyncCronExpression?
> I add some log output at the end. In that case the StaleWorkflowsHealthCheck
> should be executed every 5 minutes (asyncCronExpression = "0 0/5 * * * ? *")
> Thanks for your help.
