             Summary: Apache Felix SCR Lock timeout
                 Key: FELIX-6288
                 URL: https://issues.apache.org/jira/browse/FELIX-6288
             Project: Felix
          Issue Type: Bug
          Components: Declarative Services (SCR)
            Reporter: Peter Kriens


The SCR timeout for obtaining the lock to create a component instance (state lock) is 5 secs. We ran into a case where this was not sufficient on embedded hardware. Clearly an activate method/constructor should not take this amount of time. However, while tracing this it was clear that this time included a large number of activate methods. If you have a set of lazy services in a dependency chain, and someone activates the top of the chain, all downstream activate methods will be running.

The purpose of the 5 secs is imho to break deadlocks, there seems nothing to win by breaking an application because you only want to wait 5 secs. If an application takes too long to startup, it is far superior to let the application finish correctly than put it in an unknown state by failing the component creation.

I suggest increasing the default timeout to something like 30sec. This will break deadlocks and should handle the 99,999% of the cases slowly but correctly.
