Ted Ross resolved QPID-1088.
----------------------------
Resolution: Fixed
> Locking cleanup for management objects
> --------------------------------------
>
> Key: QPID-1088
> URL: https://issues.apache.org/jira/browse/QPID-1088
> Project: Qpid
> Issue Type: Improvement
> Components: C++ Broker
> Affects Versions: M3
> Reporter: Ted Ross
> Assignee: Ted Ross
> Priority: Minor
> Fix For: M3
>
>
> A recent change to the management code generator caused excessive locking
> during the increment and decrement of counter statistics in management
> objects.
> This update does the following:
> 1) Change RW locks in management objects to Mutexes
> 2) Remove locking for increment and decrement operations on counters
> 3) Provide user access to the management object mutex
> 4) Add higher-level locking in the broker::Queue class to protect all counter
> operations as a block.
> There should now be only one lock taken out for management during the
> production or consumption of a message.
