---------------------------------------
Summary: Installing subsystem with large number of constituents
takes forever or gives out of memory
Key: ARIES-1459
URL: https://issues.apache.org/jira/browse/ARIES-1459
Project: Aries
Issue Type: Bug
Components: Subsystem
Affects Versions: subsystem-2.0.6
Reporter: David Bosschaert
Installing a large subsystem that contains a lot of bundles can cause the
resolution phase to run for hours and sometimes causes out of memory.
I think this is cause by the fact that all the bundles inside the subsystem are
attempted to be resolved in one shot. When you have 200+ bundles that gives an
enormous resolution problem space.
In a plain OSGi framework such a scenario can be helped by installing bundles
in stages, making life easier for the resolver.
Maybe subsystems can support this too. We could use the 'start-order' directive
on the Subsystem-Content header to guide resolution and only resolve bundles on
the current start-order as we progress through those.
