------------------------------------
Summary: Increase timeout for subsystem locking strategy and make
it configurable
Key: ARIES-1609
URL: https://issues.apache.org/jira/browse/ARIES-1609
Project: Aries
Issue Type: Bug
Reporter: Thomas Watson
With a large number of large subsystems the contention for the locks managed by
LockingStrategy class in subsystems may be very high. The current timeout is
hardcoded to 30 seconds. In scenarios that use provision dependencies at start
(instead of at install) this contention may increase if a large number of
subsystems are staged and are in the state waiting to provision dependencies.
Once the first subsystem is started it may result in a very large number of the
currently installed subsystems to all provision dependencies at once. This can
take over 30 seconds. If multiple threads are attempting to start the
subsystems at the same time this may cause the timeout for the losing threads.
I think the default timeout should be increased to something pretty large. I
suggest 10 minutes. And we should likely allow a property to override the
default timeout.
