Felix Meschberger resolved FELIX-3039.
--------------------------------------
Resolution: Fixed
Fix Version/s: scr-1.6.2
Assignee: Felix Meschberger
In Rev. 1185082: Added new ds.delayed.keepInstances configuration property
which allows to prevent delayed components from being clean up. By default this
property is false (to implement the spec suggestion). The property can be set
as a framework property or as part of the org.apache.felix.scr.ScrService
configuration.
Also updated documentation at
http://felix.apache.org/site/apache-felix-service-component-runtime.html#ApacheFelixServiceComponentRuntime-Configuration
> SCR cleans up delayed service components too aggressively

> URL: https://issues.apache.org/jira/browse/FELIX-3039
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Reporter: Neil Bartlett
> Assignee: Felix Meschberger
> Priority: Minor
> Fix For: scr-1.6.2

>
> In the case of an ordinary delayed service component, SCR immediately
> deactivates and destroys the component when its service is released by the
> consumer. In cases where a consumer occasionally binds and invokes the
> service (e.g. EventAdmin) this can cause the component to be continuously
> destroyed and recreated.
> Note that Equinox's DS offers a little more control, we can choose either to
> immediately clean up or never clean up (and the default is never). This is
> still not very satisfactory though.
> I think ideally there should be a configurable timeout, so that a component
> will be cleaned up only if it is not used for some time. I also think the
> default should be quite long, e.g. many minutes.
