SCR cleans up delayed service components too aggressively
---------------------------------------------------------
Key: FELIX-3039
URL: https://issues.apache.org/jira/browse/FELIX-3039
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Reporter: Neil Bartlett
Priority: Minor
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.
